That's a ruby string, you can put whatever ruby expression you want

you press submit

You can via update_page (an ajax responder is often cleaner though).
You'll write better JS once you get over RJS

Personally I would do that via an ajax callback. The code for submit
looks it would undisable the button if the onsubmit returns false
(which the one remote_form_for will do since it's preventing the
browser from submitting the form normally)
