Events on Sortable drag and drop items - question

Events on Sortable drag and drop items - question

Hi
I'm trying to get drag item details on receive event but couldnt understand from documentation how its being done.
My code loks like this:

// Supply a callback function to handle the receive event as an init option.

        $("#sortable1" ).sortable({
            receive: function(event, ui)
            {              
                var items = $( "#sortable1" ).sortable( "option", "ui.item" );
                alert(items);
            }
        });

        //Bind to the receive event by type: sortreceive.

        $( "#sortable1" ).bind( "sortreceive", function(event, ui) {
             var items = $( "#sortable1" ).sortable( "option", "ui.item" );
             alert(items);
        });

Need assistance
Thanks..
