How to perform checkbox checkevent? - extjs

Question

I want a help for performing checkevent in a check box. Here is my code:
View.js:
Ext.define('AM.view.shop.Bill',
{
extend: 'Ext.form.Panel',
alias : 'widget.bil',
title: 'Complete Check Out',
defaultType:'textfield',
initComponent: function() {
this.items= [
// Mailing Address
{ xtype: 'fieldset',
title: 'Mailing Address',
defaultType: 'textfield',
layout: 'anchor',
width:520,
defaults: {
anchor: '100%'
},
items: [{
fieldLabel: 'Street Address',
name: 'mailingStreet',
billingFieldName: 'billingStreet',
allowBlank: false
},
{ xtype: 'container',
layout: 'hbox',
items: [{
xtype: 'textfield',
fieldLabel: 'City',
name: 'mailingCity',
id:'mailingCity',
billingFieldName: 'billingCity',
flex: 1,
allowBlank: false
}]
}]
},
// Billing Address
{
xtype: 'fieldset',
title: 'Billing Address',
layout: 'anchor',
width:520,
defaults: {
anchor: '100%'
},
items: [{
xtype: 'checkbox',
name: 'billingSameAsMailing',
boxLabel: 'Same as Mailing Address?',
hideLabel: true,
checked: true,
style: 'margin-bottom:10px',
id:'billingSameAsMailing',
},
{ xtype: 'textfield',
fieldLabel: 'Street Address',
name: 'billingStreet',
//style: 'opacity:.3',
disabled: true,
allowBlank: false
},
{ xtype: 'container',
layout: 'hbox',
items: [{
xtype: 'textfield',
fieldLabel: 'City',
name: 'billingCity',
id:'billingCity',
style: (!Ext.isIE6) ? 'opacity:.3' : '',
flex: 1,
disabled: true,
allowBlank: false
}]
}]
}]
this.callParent(arguments);
}
});
controller.js:
Ext.define('AM.controller.Shops', {
extend: 'Ext.app.Controller',
init: function() {
this.control({
'bil textfield[name=mailingCity]' : {
change: function(textField) {
var formpanel = Ext.ComponentQuery.query('bil')[0];
var copyToBilling = formpanel.down('[name=billingSameAsMailing]').getValue();
if (copyToBilling) {
var city=formpanel.down('[name=mailingCity]').getValue();
formpanel.down('[name=billingCity]').setValue(city);
}
}
},
'bil checkbox[name=billingSameAsMailing]': {
check: function(item, checked) {
alert(item);
}
}
});
}
});
I use the same method of textbox, to get a particular checkbox for performing event on
that checkbox. In textbox it's working correctly but in the case of checkbox it does not respond.
