title: Sencha Touch 2.0.0 - store.load not calling on pagingation
body: <p>Hi I am new to Sencha touch and using <code>Ext.dataview.DataView</code> to display a list of products.</p>
  
  <p>I am using plugin <code>Ext.plugin.ListPaging</code> for automatic pagination.
  In constructor of my <code>Ext.dataview.DataView</code> class, I am creating an instance of <code>store</code> and adding an event listener on it.</p>
  
  <pre><code>var store = Ext.create('MyApp.stores.Products', sale);
  store.load(function(results) {
  // My implementation here
  });
  </code></pre>
  
  <p>Every thing is working perfect, except the <code>store.load</code> event is called only once first 25 records are fetched. When user scrolls down, more records are populated in list but <code>store.load</code> doesn't call again.</p>
  
  <p>I need to add some custom code in <code>store.load</code>.</p>
  
  <p>Any idea what's wrong?</p>
