  <pre><code>Ext.define('MyApp.store.myStore', {    extend: 'Ext.data.Store',
  requires: [
      'Ext.data.Field'
  ],
  
  constructor: function(cfg) {
      var me = this;
      cfg = cfg || {};
      me.callParent([Ext.apply({
          storeId: 'myStore',
          fields: [
              {
                  name: 'nameField'
              }

      var comp = component.up('#viewContainer');
      var tgrid = comp.down('#netTable');
      console.log(component);

  <pre><code>var store =  Ext.getStore('myStore');
  var menuPoint = Ext.create('Sencha.model.MenuPoint', 
     {
          nameField: 'child'
      });
