I have also found I could do something like this:

    start: function(e, ui) {
        // creates a temporary attribute on the element with the old index
        $(this).attr('data-previndex', ui.item.index());
    update: function(e, ui) {
        // gets the new and old index then removes the temporary attribute
        var newIndex = ui.item.index();
        var oldIndex = $(this).attr('data-previndex');

but still..I don't how to build a callback or something so that to receive
that new and old index at the server side.

Any help is appreciated.
