The recent optimization for inlineEditor resulted in fields that could

not be saved, due to the dirty state not yet being updated.
Now, we force a calculation when we need the value. It will result in an

extra calculation, since a _.throttle can't be canceled, but it

shouldn't have any noticeable impact, as it occurs only on save/cancel

or when specifically requesting the dirty state.

Tested saving and canceling fields. Didn't have any problems.
