title: Sencha Touch 2.1: Tap event seems only to work with img, but not with a carousel
body: <p>I build a Carousel containing containers with two items each: an image and a dataview. On click I want to flip the image to show the dataview. My problem is that the tap event doesn't fire on the right element. It fires on an 'img'-element, but not on the carous.</p>
  
  <pre><code>Ext.define('MY.controller.Mycarousel' , {
  extend: 'Ext.app.Controller',
  requires: [ 'Ext.Img' ],
  
  config: {
      refs: {
          mycarouselView: '#mycarousel',
      },
  
      control: {
          mycarouselView: {
              activate: 'flipImage',          // works
              tap: 'flipImage',               // doesn't work
          },
          'img': {
              tap: 'flipImage',               // works
          }
      }
  },
  </code></pre>
  
  <p>How can I get the tap event on a carousel view?</p>
  
  <p>I also tried:</p>
  
  <pre><code>Ext.define('MY.controller.Mycarousel' , {
  extend: 'Ext.app.Controller',
  requires: [ 'Ext.Img' ],
  
  config: {
      refs: {
          myCarouselDataview: 'dataview'
      },
  
      control: {
          myCarouselDataview: {
              initialize: 'flipImage',     // fires
              itemsingletap: 'flipImage',  // doesn't fire
              itemtap: 'flipImage',        // doesn't fire
              itemtouchstart: 'flipImage'  // doesn't fire
          },
          'img': {
              tap: 'flipImage', // fires
          },
      }
  },
  </code></pre>
  
  <p>If I click on the image, the image is flipped, the dataview appears, shows its html, but if I click on it then no events are fired. That's mysterious to me ...</p>
