Gridview Pagination Doesn't Work After Ajax Replace.

I have the following view file:

<div class="search-form">


	<?php $model2 = new Symptoms;


	$this->renderPartial('_searchCategory', array('model'=> $model2), false, true); ?>



<div class="row" id="symptomSelectDiv" >



 	$this->renderPartial('_symptomsGrid', array('model'=> $model2)); 




The 2 subviews are



    	echo	CHtml::dropDownList('symptomCategory', 'symptomCategory',



                                                  'prompt'=>"Select Symptom Category",  

                                            		  'ajax'=> array(




                                            					'data'=>array('symptomCategory'=>'js:this.value', 'YII_CSRF_TOKEN' => Yii::app()->request->csrfToken))                                                                            






$this->widget('zii.widgets.grid.CGridView', array(


		'selectableRows'=>1, //ability to select one symptom at a time









)); ?>

The controller action that replaces the grid with the new one is:

public function actionUpdateSymptomsGridView()


		$symptomsModel = new Symptoms;







			 $this->renderPartial('_symptomsGrid', array('model'=>$symptomsModel), false, true);



The problem is that when the new gridview loads and I go to a different page of its pagination it doesn’t load and instead I lose the entire gridview (I checked my html with firebug, there’s nothing being rendered).

Can anyone help me please?
