Yii Sort By Clistview not working - php

Question

I'm using Yii 1.1.15. I got to my CListView to populate the table correctly on page load. but when i try to sort the table by store name the ajax response is the html for the whole page. and the table is empty.
but when i refresh the page &sort=store or &sort=store.desc the page works fine and sorts proper too. Any ideas what i'm doing wrong?
In my Controller
$dataProvider=new CActiveDataProvider('Store',
array(
'criteria' => array(
'condition'=>$_search_conditions,
'params'=>$search_params,
),
'sort'=>array(
'defaultOrder'=>'store DESC',
'attributes'=>array(
'store'=>array(
'asc'=>'store',
'desc'=>'store DESC',
),
'*',
)
),
)
);
$model = new Store;
$model->unsetAttributes(); // clear any default values
//render page
$this->render('index',array(
'dataProvider'=>$dataProvider,
'model'=>$model
));
In my View
$this->widget('zii.widgets.CListView', array(
'id' => 'store-list',
'dataProvider'=>$dataProvider,
'itemView'=>'_view',
'enableHistory'=> true,
'pagerCssClass' => 'pagination',
'ajaxUpdate'=>'store-list',
'loadingCssClass' => '', //remove loading icon
'sortableAttributes'=>array(
'store',
//'state' => 'State',
//'distance' => 'Distance'
),
'emptyText' => '<div class="alert alert-info">No data found</div>',
'template'=>'
<div class="row">
<div class="col-md-12">
<div class="pull-left visible-lg visible-md visible-sm">{summary}</div>
<div class="pull-right">{sorter}</div>
</div>
</div>
<div class="row">
<div class="col-md-12">{items}</div>
</div>
<div class="row">
<div class="col-md-12">
{pager}
</div>
</div>',
'pager' => array('id'=>'_pagination',
'class' => 'LinkPager',
'header' => '', //remove pagination header
'htmlOptions'=>array('class'=>'pagination') //add bootstrap pagination class
),
));
also in my function parseUrl() i have this code which does echo the correct value for $_GET['Store_sort'] the code below is used in my custom url manager class
if (!empty($_GET['sort']))
{
echo $_GET['Store_sort'] = $_GET['sort'];
}
UPDATE: even with friendly url disabled it does not sort. here is the URL of the ajax post. The pagination doesnt work either
