Jquery Sortable Update Event can called only one time?

Question

Hello. I'm trying to make category changes with Jquery & Php. I have no problem with it. My problem is, when the update event is called, it returning 2 results. 1 result for Dragged Parent, One result for Dropped Parent. I wanna call only dropped parent's id. Here is my script:

$("#gallery ul").sortable({
    connectWith: '.dropBox',
    opacity: 0.35,
    scroll: true, 
    scrollSensitivity: 100,
    //handle: '.move',
    helper: 'clone',
    containment:'#gallery',
    accept:'#gallery > .photo',
    revert: true,
    update: function(event, ui){
        params = 'c=' + $(this).attr('id') + '&id=' + ui.item.attr('id');

        $.ajax({
            type: 'POST',
            url: 'processData.php',
            data: params,
            error:function(){
                alert("Error!");
            },
            success:function(data){
                $("#serverResponse").html(data);
            }
        });
    }
}).disableSelection();

Can you help me guys?

You should try to play with the sortable different events

• start
• sort
• change
• beforeStop
• stop
• update
• receive
• remove
• over
• out
• activate
• deactivate

I'm pretty sure one of'em will be your answer.
