title: How to add a custom update on a pull refresh?
body: <p>In the standard "Pull to Refresh" plugin, the list store gets updated.  However, I have two lists and I need to update a different store for my detail list.  How can I override the update event and reload my other store?  I tried adding a simple listener but it's not firing.</p>
  
  <p>[Update]</p>
  
  <p>I got this snippet from the <a href="http://www.sencha.com/forum/showthread.php?184612-Documentation-pullRefresh-Example-and-can-t-post-comments" rel="nofollow">Sencha site</a> to work:</p>
  
  <pre>
  plugins: [
            {
               xclass: 'Ext.plugin.PullRefresh',
                pullRefreshText: 'Pull down for more new Events!',
                refreshFn: function(plugin) {
                    console.log( "I'm pulled" );
                }
             }
            ]
  </pre>
  
  <p>Original code:</p>
  
  <pre>
  Ext.define('SenchaFiddle.view.ListView', {
      extend: 'Ext.dataview.List',
      xtype: 'main-list',
  
      config: {
          plugins: [
              'pullrefresh',
              {
                  pullRefreshText: 'Do it!',
                  type: 'listpaging',
                  // Don't offer "Load More" msg
                  autoPaging: false,
  <b>
                  refreshFn: function() {             
                    console.log("Boom");
                  },
  
                  listeners: {
                      'updatedata': function(plugin, list) {
                          console.log("Getting the data");
                      }
                  }
  </b>
              }
          ],
          layout: 'fit',
          width: 300,
          itemTpl: '{text}'
  
      }
  });
