title: Scroller events don't fire in Sencha Touch
body: <p>I configured scroll events in a dataview but they don't fire. The rest of scrollable configuration is OK, just the listeners conf doesn't seem to be considered. Any clue ?</p>
  
  <pre><code>{   itemId:'names',
      xtype:'dataview',
      disableSelection:true,
      scrollable:{
          direction:'vertical',
          listeners:{
              scroll:function(){
                  console.log('[scrollable][on scroll]');
              },
              scrollend:function( scroller, x, y, eOpts ){
                  console.log('[scrollable][on scrollend]x='+x+', y='+y);
              }
          }
      },
      store:{
              fields:['name'],
              data:[{name:'Cherif'}]
      },
  
      itemTpl:'{name}'
  }
  </code></pre>
