Can we implement On key up filter option in Yii's cGridview?

I am currently trying to implement automatic filtering in Yii cGridview, By default it filters 'onclick', or 'enter' key press, But I need to change that event to "onkeyup"|

my code is like this

Yii::app()->clientScript->registerScript('search',"   
    $('.filters > td >input').keyup(function(){    
        $('#grid-id').yiiGridView('update', {
            data: $(this).serialize()  
        });
        return false; 
    });
"); 
?>

when I entered the first letter filtering occured, but after filtering and rendering the code fails.. please give me a solution.. Is there any php yii gridview extension which has filtering onkeyup

You need to change the way you attach the keyup listeners. After the gridview refreshed through AJAX, all elements inside the grid are replaced. So there's no keyup attached anymore. You can try something like:

$('body').on('keyup','.filters > td > input', function() {
    $('#grid-id').yiiGridView('update', {
        data: $(this).serialize()  
    });
    return false; 
});
