I would be inclined to just use an event handler (onchange, oninput, or
onfocus) to detect when the fields have been filled in, do a jquery call to
your controller, and refresh your div. The other approach may be to
calculate amt in the javascript, which may involve having a hidden field in
your form for the usage-price rate.
