title: How to get values from Extjs getUpdatedRecords()?
body: <p>When I try to retrieve just <code>grid.getStore().getUpdatedRecords()</code>, it works just fine, but when trying to enter that object and retrieve data from(data), I get <em>is undefined</em><br/></p>
  
  <pre><code>plugins: [
      Ext.create('Ext.grid.plugin.RowEditing', {
          clicksToMoveEditor: 1,
          listeners: {
              'edit': function () {
  
                      var grid = Ext.getCmp('dataGrid');
                      var editedRecords = grid.getStore().getUpdatedRecords(); // &lt;---- OK
                    //var editedFirstName = editedRecords.data.FirstName;
                    //console.log(editedFirstName);
                      console.log(editedRecords);
                  }
  
           }
      })
  ]
  </code></pre>
  
  <p><br/>
  Here is my Firebug showing that this object has <em>data.FirstName, data.LastName, data.id</em></p>
