As of Rails 4, you should be able to ditch all the JS from the original answer. The code in your question should just work due to jQuery UJS magic.
It turns out that adding remote: true to an input causes jquery-ujs to make it ajax-y in all the nice ways. Thoughtbot's "A Tour of Rails jQuery UJS" briefly touches this (and many other good things available); the "Unobtrusive scripting support for jQuery" page in the jQuery UJS wiki does a thorough job on this as well.
