Phonegap , Barcode Scanner not working on android - phonegap-plugins

Question

I have done the following to install and use the barcode scanner.
>phonegap plugin add https://github.com/jonathannaguin/BarcodeScanner
this successfully installed the barcode scanner plugin in the phonegap/plugins directory.
Then i built it for android like this
phonegap build android
This also finished successfully. Then i placed this in a sencha touch app using a handler on a text field. But when the field is tapped there is no result. Nothing happens.
Ext.define("Tasks.view.BarcodeField", {
extend: 'Ext.Container',
alias:'widget.barcodeField',
xtype: 'barcodefield',
config: {
layout: 'hbox',
id: 'barcodeField',
itemId: 'barcodeField',
items: [
{
xtype: 'textfield',
label: 'Barcode',
labelWidth: '37.4%',
flex: 4
},
{
xtype: 'image',
id : 'barcodeScanner',
itemId : 'barcodeScanner',
src: 'resources/images/barcodes.png',
padding: '6 0 0 0',
flex: 1,
listeners: {
tap: function() {
console.log("Starting the barcode Scanner");
function success(result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
}
function fail(error) {
alert("Scanning failed: " + error);
}
cordova.plugins.barcodeScanner.scan(success, fail);
}
}
}
]
},
getValue : function()
{
console.log(this.getItems().getAt(0).getValue());
return this.getItems().getAt(0).getValue();
},
setValue : function(newvalue) {
this.getItems().getAt(0).setValue(newvalue);
}
});
I see the tap handler is being invoked and the log statement on the console.

I have the call to the barcode plugin to the following and it is working. Instead of calling cordova.plugins i used window.plugins and it works.
Ext.define("Tasks.view.BarcodeField", {
extend: 'Ext.Container',
alias:'widget.barcodeField',
xtype: 'barcodefield',
config: {
layout: 'hbox',
id: 'barcodeField',
itemId: 'barcodeField',
items: [
{
xtype: 'textfield',
label: 'Barcode',
labelWidth: '37.4%',
flex: 4
},
{
xtype: 'image',
id : 'barcodeScanner',
itemId : 'barcodeScanner',
src: 'resources/images/barcodes.png',
padding: '6 0 0 0',
flex: 1,
listeners: {
tap: function() {
console.log("Starting the barcode Scanner");
function success(result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
}
function fail(error) {
alert("Scanning failed: " + error);
}
window.plugins.barcodeScanner.scan(success, fail);
// cordova.plugins.barcodeScanner.scan(success, fail);
}
}
}
]
},
getValue : function()
{
console.log(this.getItems().getAt(0).getValue());
return this.getItems().getAt(0).getValue();
},
setValue : function(newvalue) {
this.getItems().getAt(0).setValue(newvalue);
}
});
