PolymerJs aha-table event for "selectable" checkbox

I am trying to implement aha-table using Polymer Js. While creating the table I have kept "selectable" attribute true and as expected I am getting the checkboxes before each row, so, I would like to know is there a way to handle/catch the check/unckeck event of such checkboxes. I am able to handle the cell click event for a cell with "after-td-click" event.

I could not find any any such event for the same.

Thanks for your help in advance and please let me know if you need more info on the same.
