在yii中更新cgridview后，Jquery UI排序不起作用

我正在处理一个基于AJAX请求（无重载）的项目。在我们更新cgridview之前，Jquery sortable运行良好，之后它就不工作了。

此外，如果我多次排序，它就会停止工作。这个页面有很多图片列表。

我有一个代码如下：|

index.php

//Get image details
foreach($arrContent as $key => $value) {
    ob_start();
        $this->widget('ImageWidget',array('imageModel'=>new Images(),'entityType'=>$key,'entityTypeId'=>$specModel->spec_id,'type'=>'View'));
        $arrContent[$key] = ob_get_contents();
    ob_end_clean();
    ob_start();
        $this->widget('ImageWidget',array('imageModel'=>new Images(),'entityType'=>$key,'entityTypeId'=>$specModel->spec_id,'type'=>'Form'));
        $arrContent[$key] .= ob_get_contents();
    ob_end_clean();
}
ob_start();
    $this->widget('BrochureWidget',array('brochureModel'=>new Brochure(),'entityType'=>"SPEC", 'entityTypeId'=>$specModel->spec_id,'type'=>'Form'));
    $brochureContent .= ob_get_contents();
ob_end_clean();
$this->widget('zii.widgets.jui.CJuiTabs',array(
    'tabs'=>array(
        "Brochure({$countBrochure})"=>array(
            'content'=>$brochureContent,
        ),
        "Elevation Images({$countElevationImages})"=>array(
            'content'=>$arrContent['SPEC_ELEVATION']
        ),
    ),
)
