title: How to get items in extjs
body: <p>In my project, I created <code>widget alias</code> for the below code in "View" as <code>notifications</code>. Now, how to access each and every item in "Controller" ?</p>
  
  <pre><code>extend: 'Ext.panel.Panel',
  alias: 'widget.notifications',
  layout: 'fit',
  items:[{
      xtype: 'container',
      layout: {type: 'vbox', align: 'stretch'},
      items: {
          xtype: 'container',
          flex:1,
          layout: {type: 'vbox', align: 'stretch'},
          items:[{
              xtype: 'container',
              flex: 1,
              items: [{
                  xtype: 'container',
                  height: 20,                 
                  html: "This week",                  
              },
              {
                  xtype: 'container',
                  flex: 1,
                  layout: {type: 'vbox', align: 'stretch'},
                  items: [{
                      xtype: 'container',
                      height:20,
                      html : 'show submit status here'
                  },
                  {
                      xtype: 'container',
                      flex: 1,
                  }]
              }]
          },
          {
              xtype: 'container',
              flex: 1,
              layout: {type: 'vbox', align: 'stretch'},
              items: [{
                  xtype: 'container',
                  height: 20,
                  html: "This month"
              },
              {
                  xtype: 'container',
                  flex: 1,
                  layout: {type: 'vbox', align: 'stretch'},
                  items: [{
                      xtype: 'container',
                      html: 'submit status of month here',
                      height: 20
                  },
                  {
                      xtype: 'container',
                      flex: 1,
                  }]
              }]
          }]
      }
  }]
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code> var notificationView = Ext.widget('NotificationView');
   var childItem = notificationView.items.items[0].items.items[0].items.items[0].items.items[0];
  </code></pre>
  
  <p>Which just gives me headache and many errors.</p>
  
  <p>I also tried using ComponentQuery like this:</p>
  
  <pre><code>var childItem = notificationView.ComponentQuery.query('container&gt;container&gt;container&gt;container');
  </code></pre>
  
  <p>Which gets only the first child, not the other child items.</p>
