PageSize not working on Grid in ExtJS - extjs

Question

I want to limit the records per page to a specific number apply paging in the grid but its failing due to some reason.
Can anyone say why it's failing, or not working? Here's the Fiddle.
My Store
var myStore=Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['busname', 'time', 'typebus',],
pageSize:2,
data: [{
busname: 'ABCD',
time: '15:30:00',
typebus: 'AC Volvo',
}, {
busname: 'aaa',
time: '13:30:00',
typebus: 'Seater',
},{
busname: 'AAAA',
time: '18:30:00',
typebus: 'Sleeper',
},{
busname: 'ABCD',
time: '19:30:00',
typebus: 'AC Volvo',
},]
Grid panel
Ext.create('Ext.grid.Panel', {
xtype :'gridpanel',
itemId:'busTimegrid',
pageSize:1,
title: 'BUS DEATILS',
mapperId:'getBusTime',
store: Ext.data.StoreManager.lookup('simpsonsStore'),
columns: [{
header: 'Bus Name',
dataIndex: 'busname',
editor: 'textfield'
}, {
text: 'Bus Time',
dataIndex: 'time',
xtype: 'gridcolumn',
renderer: function (value) {
if (value instanceof Date)
         return Ext.util.Format.date(value, 'H:i:s');
     else
     return value;
},
flex: 1,
editor: {
xtype: 'timefield',
format: 'H:i:s',
allowBlank: true,
maskRe: /[0-9,:]/,
}
}, {
header: 'Bus TYpe',
dataIndex: 'typebus',
editable:true,
renderer: function (value) {
if (Ext.isNumber(value)) {
var store = this.getEditor().getStore();
return store.findRecord('id', value).get('name');
}
return value;
},
editor: {
xtype: 'combo',
displayField: 'name',
valueField: 'id',
editable:true,
forceSelection:true,
store: Ext.create('Ext.data.Store', {
fields: ['id', 'name'],
data: [{
id: 1,
name: 'AC Volvo'
}, {
id: 2,
name: 'Seater'
}, {
id: 3,
name: 'Sleeper'
}]
})
}
}],
selModel: 'cellmodel',
plugins: {
ptype: 'cellediting',
clicksToEdit: 1,
},
listners: [{
fn: 'onUsernamefieldBlur',
event: 'blur',
delegate: 'busname'
}],
onUsernamefieldBlur: function (textfield, e, eOpts) {
if (textfield.getValue() === '') {
Ext.Msg.alert("Busname can't be empty");
textfield.setFocus(true);
}
},
height: 200,
width: 400,
dockedItems: [{
xtype: 'pagingtoolbar',
store: myStore, // same store GridPanel is using
dock: 'bottom',
displayInfo: true
}],
renderTo: Ext.getBody()
});
Added the pageSize but still the paging is not working. I don't seem to find out what's the issue. How can I find out the exact thing I'm missing?

Answer 1

From your question I observed you want to achieve local pagination which is different from actual pagination. To do this first you need to mention memory proxy and enable the pagination , Put my below code in your store.
proxy: {
type: 'memory',
enablePaging: true
}
I am able to get the pagination by putting the above proxy in your fiddle.

(Posted on behalf of the OP).
This worked fine, after I followed what Surya prakash suggested a solution.
Ext.application({
name: 'Fiddle',
launch: function () {
run();
window.show();
}
});
function run() {
var myStore=Ext.create('Ext.data.Store', {
storeId: 'simpsonsStore',
fields: ['busname', 'time', 'typebus',],
pageSize:2,
proxy: {
type: 'memory',
enablePaging: true
},
data: [{
busname: 'ABCD',
time: '15:30:00',
typebus: 'AC Volvo',
}, {
busname: 'aaa',
time: '13:30:00',
typebus: 'Seater',
},{
busname: 'AAAA',
time: '18:30:00',
typebus: 'Sleeper',
},{
busname: 'ABCD',
time: '19:30:00',
typebus: 'AC Volvo',
},]
});
Ext.create('Ext.grid.Panel', {
