Reconfigured Grid does not work on ExtJS 4.2 - node.js

Question

I'm trying to use a reconfigure grid on extjs 4.2, you can find its example with its original code here (go to Reconfigure Grid under Grids) but it doesn't find the file Office.js and Empolyee.js.
Code:
function init() {
Ext.application({
name: 'MyApp',
launch: function() {
const grid = Ext.define('KitchenSink.view.grid.Reconfigure', {
extend: 'Ext.container.Container',
requires: [
'Ext.grid.*',
'Ext.layout.container.HBox',
'Ext.layout.container.VBox',
'KitchenSink.model.grid.Office',
'KitchenSink.model.grid.Employee'
],
xtype: 'reconfigure-grid',
layout: {
type: 'vbox',
align: 'stretch'
},
width: 500,
height: 330,
lastNames: ['Jones', 'Smith', 'Lee', 'Wilson', 'Black', 'Williams', 'Lewis', 'Johnson', 'Foot', 'Little', 'Vee', 'Train', 'Hot', 'Mutt'],
firstNames: ['Fred', 'Julie', 'Bill', 'Ted', 'Jack', 'John', 'Mark', 'Mike', 'Chris', 'Bob', 'Travis', 'Kelly', 'Sara'],
cities: ['New York', 'Los Angeles', 'Chicago', 'Houston', 'Philadelphia', 'Phoenix', 'San Antonio', 'San Diego', 'Dallas', 'San Jose'],
departments: ['Development', 'QA', 'Marketing', 'Accounting', 'Sales'],
initComponent: function(){
Ext.apply(this, {
items: [{
xtype: 'container',
layout: 'hbox',
defaultType: 'button',
items: [{
itemId: 'showOffices',
text: 'Show Offices',
scope: this,
handler: this.onShowOfficesClick
}, {
itemId: 'showEmployees',
margin: '0 0 0 10',
text: 'Show Employees',
scope: this,
handler: this.onShowEmployeesClick
}]
}, {
margin: '10 0 0 0',
xtype: 'grid',
flex: 1,
columns: [],
viewConfig: {
emptyText: 'Click a button to show a dataset',
deferEmptyText: false
}
}]
});
this.callParent();
},
onShowOfficesClick: function(){
var grid = this.down('grid');
Ext.suspendLayouts();
grid.setTitle('Employees');
grid.reconfigure(this.createOfficeStore(), [{
flex: 1,
text: 'City',
dataIndex: 'city'
}, {
text: 'Total Employees',
dataIndex: 'totalEmployees',
width: 140
}, {
text: 'Manager',
dataIndex: 'manager',
width: 120
}]);
this.down('#showEmployees').enable();
this.down('#showOffices').disable();
Ext.resumeLayouts(true);
},
onShowEmployeesClick: function(){
var grid = this.down('grid');
Ext.suspendLayouts();
grid.setTitle('Employees');
grid.reconfigure(this.createEmployeeStore(), [{
text: 'First Name',
dataIndex: 'forename'
}, {
text: 'Last Name',
dataIndex: 'surname'
}, {
width: 130,
text: 'Employee No.',
dataIndex: 'employeeNo'
}, {
flex: 1,
text: 'Department',
dataIndex: 'department'
}]);
this.down('#showOffices').enable();
this.down('#showEmployees').disable();
Ext.resumeLayouts(true);
},
createEmployeeStore: function(){
var data = [],
i = 0,
usedNames = {},
name;
for (; i < 20; ++i) {
name = this.getUniqueName(usedNames);
data.push({
forename: name[0],
surname: name[1],
employeeNo: this.getEmployeeNo(),
department: this.getDepartment()
});
}
return new Ext.data.Store({
model: KitchenSink.model.grid.Employee,
data: data
});
},
createOfficeStore: function(){
var data = [],
i = 0,
usedNames = {},
usedCities = {};
for (; i < 7; ++i) {
data.push({
city: this.getUniqueCity(usedCities),
manager: this.getUniqueName(usedNames).join(' '),
totalEmployees: Ext.Number.randomInt(10, 25)
});
}
return new Ext.data.Store({
model: KitchenSink.model.grid.Office,
data: data
});
},
// Fake data generation functions
generateName: function(){
var lasts = this.lastNames,
firsts = this.firstNames,
lastLen = lasts.length,
firstLen = firsts.length,
getRandomInt = Ext.Number.randomInt,
first = firsts[getRandomInt(0, firstLen - 1)],
last = lasts[getRandomInt(0, lastLen - 1)];
return [first, last];
},
getUniqueName: function(used) {
var name = this.generateName(),
key = name[0] + name[1];
if (used[key]) {
return this.getUniqueName(used);
}
used[key] = true;
return name;
},
getCity: function(){
var cities = this.cities,
len = cities.length;
return cities[Ext.Number.randomInt(0, len - 1)];
},
getUniqueCity: function(used){
var city = this.getCity();
if (used[city]) {
return this.getUniqueCity(used);
}
used[city] = true;
return city;
},
getEmployeeNo: function() {
var out = '',
i = 0;
for (; i < 6; ++i) {
out += Ext.Number.randomInt(0, 7);
}
return out;
},
getDepartment: function() {
var departments = this.departments,
len = departments.length;
return departments[Ext.Number.randomInt(0, len - 1)];
}
});
Ext.create('Ext.container.Viewport', {
layout: 'border',
title: "",
region: 'center',
collapsible: false,
layout: 'fit',
items: {
items: grid
},
});
}
});
}
When I try to open it on Google Chrome, I get these errors:
I have already tried to download both files from here and I put them somewhere of my project folder but the issue still persists.
Also I've tried to remove KitchenSink.model.grid.Office and KitchenSink.model.grid.Office from requires and then it works but the buttons don't work. I get this when I click on them:
Note: I'm using Node.js with Express for displaying my website since it's going to have server connections. So that's my folders tree:
-assets
|-css
|-main.css
|-util.css
|-img
|-js
|-adminPage.js (My ExtJS file)
|-jquery-3.2.1.min.js
-views
|-adminPage.ejs (I call adminPage.js from this file)
|-login.ejs
-dbConnection.js
-server.js
What am I doing wrong?

To use view you need to do Ext.create instead of Ext.define.
Instantiate a class by either full name, alias or alternate name. If Ext.Loader is enabled and the class has not been defined yet, it will attempt to load the class via synchronous loading.
Ext.define
Defines a class or override. Doesn't return anything
Btw. you should require the view definitions in Ext.app.Controller, and use alias/xtype parameter for auto-creating views by shortcut.
