Purpose ======= Onchange methods are executed in "edit-mode", so you need to save to get the definitive values saved on the DB, but if you do a write on it, that changes are immediately saved to the DB, so if you discard the changes on UI, you will have inconsistent data. That's why you have to do update instead, that only modifies the temporary dataset.
