Triggering a function with Delete button in attachments control

I am having trouble while trying to trigger a function when the user clicks on the delete button in  the attachments control. I have tried NWF$('.nf-attachmentsTable tr td.ms-propertysheet a.ms-add-new').click(function() {}); and I have tried NWF$('.ms-add-new').click(function() {}); and many others. However I am not being able to target the delete button.
Thank you!
