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>


		

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

		

<?php 

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

 ?>

	

</div>



The 2 subviews are

_searchCategory:




<?php 

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

                                             $this->getSymptomCategories(),

                                            array('id'=>'categorySelectDropDown',

                                                  'prompt'=>"Select Symptom Category",  

                                            		  'ajax'=> array(

                                            					'type'=>'POST',

                                            					'url'=>Yii::app()->createUrl('symptomhistory/updateSymptomsGridView'),

                                            					'replace'=>'#symptoms-grid',

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

                                                  ));


                                                  ?>

And

_symptomsGrid:


<?php 


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

		'id'=>'symptoms-grid',

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

		'dataProvider'=>$model->searchCategory(),

		'columns'=>array(

			'symptomCode',

			'title',

			'inclusions',

			'exclusions',

			'symptomCategory',		

		)

)); ?>

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


public function actionUpdateSymptomsGridView()

	{

		$symptomsModel = new Symptoms;


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

		{

			

			$symptomsModel->setAttributes(array(

										'symptomCategory'=>$_POST['symptomCategory']));

			


			 $this->renderPartial('_symptomsGrid', array('model'=>$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?
