how to get deleted row id in repeater control

Hi, I want to know how to get deleted row information (such as row id) in repeater control when I use NWF.FormFiller.Events.RegisterRepeaterRowDeleted function?

My Code:

NWF.FormFiller.Events.RegisterRepeaterRowDeleted(function (){
      var repeaterRow = NWF$(arguments[0][0]);
      if(NWF$(repeaterRow.parents('.nf-repeater')[0]).hasClass('AttDetail'))
      {
            console.log('row has been deleted');
      });
});
