title: Sencha Touch not firing beforeshow event listener
body: <p>Im new to sencha touch and going through the obligatory hair pulling and head2desk pounding.</p>
  
  <p>Im trying to display a List but Im having a problem.</p>
  
  <p>Im using a beforeshow event to load my json store before the list is displayed. But it's not firing the event. If any can help it is MOST appreciated.</p>
  
  <p>My code is as follows: *note- this code is AS/400 centric so the /%...%/ is for that</p>
  
  <pre><code>function doList() {                                             
          var List1 = new Ext.List  ({                            
              id : List1,                                         
              renderTo : 'panel',                                 
              fullscreen: true,                                   
              showAnimation: {                                    
                     type: 'slide',
