title: ExtJS grid selectionchange data
body: <p>I have this code:</p>
  
  <pre><code>grid.getSelectionModel().on('selectionchange', function(selModel, selections) {}
  </code></pre>
  
  <p>and inside the function with the variable 'selections' I want to get the selected row field 'name' data.<br>
  How do I do it?<br>
  I have tried 'selections.data.name' and 'selections.get('name')' but none works.<br>
  I know it's possible because Firebug shows the data of the variable 'selections'.</p>
