title: extjs 4 grid fireevent itemclick
body: <p>How do you make a <code>fireEvent</code> <code>itemclick</code> after the store loads.</p>
  
  <p>I have this but it doesn't work:</p>
  
  <pre><code>pcfstore.on('load', function(){
     //auto select first row;
     Ext.getCmp('pcf_grid').getSelectionModel().select(0); // this works
  
     //fire itemclick event
    var grid= Ext.getCmp('pcf_grid');
    grid.fireEvent('itemclick', grid, 0); //this doesnt work
  
  }); 
  </code></pre>
  
  <p>Here is my <code>itemclick</code> event in grid view:</p>
  
  <pre><code>viewConfig: {
      listeners: {
      itemclick: function(dv, record, item, index, e) {
             alert(record.data.code);
         }
      }
  }
  </code></pre>
  
  <p>Basically when the grid loads, it should fire the alert window of the selected first row
  of the grid.</p>
