Is it possible to add a pop-up once user clicks on "Delete" and ask "Are you sure? " ??

Changes otherwise looks good.

@dushimsam : Have tested this branch working perfectly. but only issue is after deleting a group page is not getting refreshed. and data still stays in select which might be confusing for user. please make the changes accordingly.
