It's difficult to answer this question because i don't really know the larger context. Usually i handle delete checkboxes and updates by iterating my list of objects returned from the screen. As i iterate through each object of the list i check to see if it is checked to be deleted and place it into a delete list. If it is not flagged for a delete i place it into an update list. Once i am finished iterating the list i pass the delete list to a delete function and my update list to an update function. Where you place this functionality in your architecture is a matter of your own judgment.
