draggable and new table

Hi,

i have ui draggable function in my site.
When i add more tables in the page then new tables don't recognise (don't work). (If I insert only one new field is still not working)

My function:
$(document).ready(function(){
        $("#Text").click(function() {
            $('<div class = "draggable"><div>Text text</div>').appendTo($('#new_table'));
        });
    });
