title: jqGrid select editOptions are not updated immediately
body: <p>I'm trying to dynamically load values into a select in a jqGrid. It almost works. The problem is that the values that are returned from the server, are not displayed until the user change row! When I debug, I can see the correc values are being set, but the selection list does not update! Using IE9.</p>
  
  <pre><code>        $("#my_grid").setColProp("master_col", { editoptions: { value: data.verksamheter, dataEvents:
          [
              { type: 'change', fn: function (e) {
                  var url = '@Url.Action("GetData", "Controller")'
                  $.getJSON(url, { id: e.srcElement.value }, function (data) {
                      $("#my_grid").setColProp("details_col", { editoptions: { value: data.verksamhetsslag} });
  
                  });
  
              } 
              }
          ]
          }
          });
  </code></pre>
