There isn't any framework-wide way to do what you want. The Dynamic*
properties were designed to change when the record changes, which is when
update() is typically called.
You could add a method to the button that binds to the LostFocus event
of the controls that affect it, and call the update() from there, but I've
never tried that myself. If you try it, let me know how (if?) it works.
