Ext.require('Ext.container.Viewport');
Ext.application({
name: 'App',
appFolder: 'app',
controllers: ['UserController'],

launch: function() {

Ext.create('Ext.container.Viewport', {
layout: 'border',
items: [
        {
            xtype: 'userList'
        }

Ext.define('App.model.UserModel',{

    {name: 'age', type: 'string'},
    {name: 'phone', type: 'string'},
    {name: 'email', type: 'string'}

File path: /app/view/UserList.js [View]

Ext.define('App.view.user.UserList' ,{
extend: 'Ext.grid.Panel',

initComponent: function() {
this.store = 'UserStore';
this.columns = [
          {text: 'Name',flex:1,sortable: true,dataIndex: 'name'},
          {text: 'Age',flex:1,sortable: true,dataIndex: 'age'},
          {text: 'Phone',flex:1,sortable: true,dataIndex: 'phone'},
          {text: 'Email',flex:1,sortable: true,dataIndex: 'email'}
        ];

this.callParent(arguments);
}

});

In fire bug it shows the JSON response as follows:

[{
  "name": "Aswini",
   "age": "32",
   "phone": "555-555-5555",
   "email": "[email protected]"
 }]

Why the Data has not been displayed although I have a valid json response. Please help!!!

Oh wat is this I have written extends instead of extend in the Store file it should be extend:'Ext.data.Model' - aswininayak
You have valid JSON response, but do you have records in the store? - sha
can you please share the solution if you have? - Patton
@Patton Check my answer, he just need to configure the reade, since he is using the generic Ext.data.Store. - VoidMain

I believe your grid did not load because you did not load the store properly. You should use.

this.getStore('userStore').load();

instead of

this.getUserStoreStore().load();

You should configure your reader in the proxy, like this:

Ext.define('App.store.UserStore', {
    extend: 'Ext.data.Store',
    model: 'App.model.UserModel',
    proxy: {
        type: 'ajax',
        url: 'app/data/contact.json',
        reader: {
            type: 'json'
        }
    }
});
