Solution: Please make sure you have defined the models config for the Store in the controller

Ext.define('IN.controller.Items', {
            extend : 'Ext.app.Controller',

            //define the stores
            stores : ['Items'],
            //define the models
            models : ['Item'],
            //define the views
            views : ['item.List', 'item.Edit', 'item.MyNumberField','item.UpperCaseTextField'],

            //special method that is called when your application boots
            init : function() {
