TableTools not working

export data and TableTools not working for me, after adding this line between head:

    <script type="text/javascript" language="javascript" src="../../components/dataTables/media/js/jquery.dataTables.min.js"></script>
    <script type="text/javascript" language="javascript" src="../../components/dataTables/media/js/ZeroClipboard.js"></script>
    <script type="text/javascript" language="javascript" src="../../components/dataTables/media/js/TableTools.js"></script>

and change table id prop in this:

    $('#myTable').dataTable({
       "sDom": '<"clear">lfrtipT'
    }); 

i can see tableTools buttons on the table but, thay are not working .
by the way, downloaded example of tableTools (TableTools-2.1.4) after adding jquery.js and jquery.dataTables.min.js to head not working.
