Why ComboBox does not trigger Form´s dirty event?

[DBApprentice]

I have a form that would disable a button if user is editing data. However, when any combobox is changed it does not fire the Dirty even of the form.

Is it s normal behavior on comboboxes?

Thanks,

Is it unbound? If so that's why, no data has changed in the record.

EDIT: It is a bound combobox, so how can I enforce it?

re-check all combos if all are bound.
the event is firing on my test.
