How to create Ajax Requests from CButton Column

Yii 1.1 General Discussion

Hello,

I have this in a column in a CGridView:


                      'anular' => array(

                        'label'=> ' Anular ',  // text label of the button

                        'url'=>'Yii::app()->controller->createUrl("anularLiquidacion",array("id"=>$data->primaryKey))',                               

                        'click'=>'function(){if(!confirm("Esta seguro que desea anular la liquidación de la cuota?")) return false;}',     // a JS function to be invoked when the button is clicked

                        'visible'=>'$data->prestamo->tipo_prestamo == "PART" && $data->estado_cuota == "' . Cuota::LIQUIDADO .  '" ',   

                        ),

In the controller , action : "actionAnularLiquidacion" I want the Crid to refresh.

I think this is why I need AjaxRequest


if (Yii::app()->getRequest()->getIsAjaxRequest())

        		Yii::app()->end();

		else

                	$this->redirect(array('view', 'id' => $p->id));

How to tell the controller that the event is AjaxRequest == true ??

Best Regards.
