Get selected row data with EDITOR

Hello,
I'm new to datatables, and i'm having a real hard time getting rows infos, to use like a shopping cart.

i tried implementing this : http://jqueryui.com/droppable/#shopping-cart with no success, being able to move only #example tbody but not #example tbody tr
Then i tried to pop up a dialog with the ROW data on click, as well no success as :

oTable = $('#example').dataTable();
 
  oTable.$('tr').click( function () {
    var data = oTable.fnGetData( this );
    alert( 'The cell clicked on had the value of '+data );
  } );

So how can i save the rows clicked/dragged/checked i don't care as long as it works as in a shopping cart to reuse after (generating a pdf with the shopping cart selected rows).

This is my last problem with this project, thanks in advance for your help :).

Edit: to get a better idea of what i'm trying to do check here http://codebin.org/view/4e666c97

Now i managed to get the selected row id, but i can't manage to return the name or anything..

		"fnRowSelected": function ( nodes ) {
						alert( 'The row with ID '+nodes[0].id+' was selected' );
						oTable = $('#example').dataTable();
						var data = oTable.fnGetData( nodes[0] );
						alert( 'The row with ID '+data+' was selected' );
                
            },
