title: jqGrid dataevent 'change' does not trigger
body: <p>I'm trying to do stuff (fill another select) when the user selects something in a select-type editor. I'm using the 'change'-event. The problem is, it does not trigger when I select someting!</p>
  
  <pre><code>    $("#my_grid").setColProp("my_col", {
          dataEvents: [
              {
                  type: 'change',
                  fn: function (e) {
                      alert("Do stuff here once I get the event to work!");
                  }
              }
          ]
      });
  </code></pre>
  
  <p>Is maybe the 'change'-event not the one to use?</p>
  
  <p>Also tried this way, in the definition:</p>
  
  <pre><code>              { name: 'my_col', index: 'my_col', width: 80, edittype: 'select', editable: true, editoptions: { dataEvents: [{ type: 'change', fn: function (e) { alert("safd") } }]} },
  </code></pre>
