[jQuery] $.ajaxStart bind on a unique element

[LostCore]

Hi!

I have this:

---------------------------------------------
        $(".submit_textarea").livequery("click", function(e){
        e.preventDefault();
        if($(this).attr("href") == "#save")
        {
                var savencancel = $(this).parent();
                var textarea = $
(this).parents(".imagencap").children("textarea");
                var caption = textarea.val();
                var idimage = textarea.attr("id");
                idimage_array = idimage.split("-");
                var maindiv = $(this).parents(".imagencap");

                        $.ajax({
                                type: "POST",
                                url: "galleries.php",
                                data: "a=jchange-
caption&id="+idimage_array[1]+"&caption="+caption,
                                success: function(data){
                                        textarea.hide("slow", function(){
                                        $(this).remove();
                                        });
                                savencancel.remove();
                                maindiv.append("<p 
id="+idimage+">"+data+"</p>");
                                }
                });
        }

------------------------------------------

and i would to show an image (the loader) only attached to the element
that have sended the ajax request (which have a unique id).

If i do

-------
$(".imagencap")
        .ajaxStart(function(){
             ....
        })
------

It will binds to all the element on the page...

Any help?
