In yii i am using Cgridview widget with pagination. Instead of that i need to load the data dynamically by scroll down event. Is there any extension?

This is the widget i am using.

<?php 
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'leave-approve-grid',
'itemsCssClass'=>'table table-bordered table-condensed table-hover table-striped dataTable',
'filter'=>$model,
'dataProvider'=>$model->approve_search(),
'enablePagination' => true,    
'pagerCssClass'=>'dataTables_paginate paging_bootstrap table-pagination',
'pager' => array('header'=>'','htmlOptions'=>array('class'=>'pagination')),
'columns' => array(             
            array(name=>'type_id', 'value'=>'$data["leave_type"]','header'=>'Leave type','filter'=>CHtml::activeDropDownList($model,'type_id',CHtml::listData($model->SelectAllLeaveType(),'type_id','type'),array('prompt'=>'All'))),
            array(name=>'staff_name','value'=>'$data["staff_name"]','header'=>'Staff Name'),
),
)
);
