Ajax submit button not updating the div

Here I am using CJuiDialog box. I have no problem with adding values in the form. It is successfully inserted in the database.

My problem is that echo "Sucessfully Added"; is not displaying in timetable.php after saving the values. Plz any help me.

timetable.php




echo CHtml::ajaxLink(Yii::t('job','Create Job'),$this->createUrl('TimetableEntries/settime'),array(

        'onclick'=>'$("#jobDialog").dialog("open"); return false;',

        'update'=>'#jobDialog','type' =>'GET','data'=>array('batch_id'=>1,'weekday_id'=>4,'class_timing_id'=>7),'dataType'=>'text',

        ),array('id'=>'showJobDialog')) ;


<div id="jobDialog"></div>



TimetableEntriesController.php




public function actionSettime()

	{


		$model=new TimetableEntries;


		  $this->performAjaxValidation($model);

		 $flag=true;

		 if(isset($_POST['TimetableEntries']))

        {    

		 $flag=false;

            $model->attributes=$_POST['TimetableEntries'];

 

            if($model->save()) {

                //Return an <option> and select it

                 echo "Sucessfully Added";

                        }

            }

		  if($flag)

		   {

                Yii::app()->clientScript->scriptMap['jquery.js'] = false;

                $this->renderPartial('create',array('model'=>$model,'batch_id'=>$_GET['batch_id'],'weekday_id'=>$_GET['weekday_id'],'class_timing_id'=>$_GET['class_timing_id']),false,true);

           }

			

	}
