NODE.JS with express website routing error - node.js

Question

I am writing a website in node.js and express. At the current moment if i run the website the login controller is loaded every time and it just loads forever.
I don't want the login controller to be loaded when i load the page. I need to to be loaded when i click on my button login.
This is my Router.js
module.exports = function(app) {
app.get('/login/:username/:password', function(req, res) {
var login = require('../controllers/login');
login.userLogin
});
app.get('/', function(req, res, next) {
res.render('index', {
title: 'Trace User Login'
});
});
}
This is my jade page
extends layout
block content
div#login
label#lblInfo Please enter your username and password.
input#txtUsername.form-control.login(placeholder='Username', type='text')
input#txtPassword.form-control.login(placeholder='Password', type='password')
a#btnLogin.btn.btn-danger.btn-lg(href='#') Login
block endContent
div.footer

How do i go about getting the login module to only load once i click on the login button. At the current moment the page is not even rendering as it is just stuck in loading my login Controller
console.log('Inside controller');
exports.userLogin = function(request, respond){
var Connection = require('tedious').Connection;
var Request = require('tedious').Request;
var config = {
userName: 'username',
password: 'password',
server: 'localhost',
options: {
instanceName: 'instance',
database: 'tempdb'
}
};
var connection = new Connection(config);
connection.on('connect', function(err) {
if (err)
console.log(err);
else
var userName = request.params.username;
var password = request.params.password;
loginRequest(userName,password);
});
};
function loginRequest(Username,Password) {
request = new Request("sp_WT_ValidateUser", function(err, rowCount) {
if (err) {
console.log(err);
} else {
console.log(rowCount + ' rows');
}
});
request.addParameter('UserName', TYPES.VarChar, Username);
request.addParameter('Password', TYPES.VarChar, Password);
request.addOutputParameter('InvalidPasswordCounter', TYPES.VarChar);
request.on('row', function(columns) {
columns.forEach(function(column) {
console.dir(column);
});
console.log('');
});
connection.execSql(request);
}

Answer 1

This seemed to fix my problems
var router = require('express').Router();
var login = require('../controllers/login');
router.post('/login', login.userLogin);
router.get('/', function(req, res, next) {
res.render('index', {
title: 'Trace User Login'
});
});
module.exports = router;
