title: How to get an element in a View from a Controller?
body: <p>I am using Sencha Touch 2,0,1.</p>
  
  <p>I need to get an element from a View in a Controller.</p>
  
  <p>At the moment I use this method, which get the View correctly, but I am not able to get the Item in the View. I do not get any error just test is undefined.</p>
  
  <p>Any ideas?</p>
  
  <p>In the Controller:</p>
  
  <pre><code>var test = this.getDetailView().items['editButton'];
  </code></pre>
  
  <p>Code in the View:</p>
  
  <pre><code>Ext.define('XXX.view.DetailView',{
     ...
  
     items: [
  
          {
              xtype: 'button',
              text: 'Edit XXX',
              ui: 'custom-btn-dwn-timetable',
              itemId: 'editButton'
          }
    ],
      ...
  }
  </code></pre>
