Nice work, thanks for sharing. I'm assuming you're the original author.

Just forked your gist and made a small update. Since 2.6 (I think) the form also needs a button parameter for submit to work.

Thanks. I am. Could be, the button parameter. Not sure, haven't been working much on these kind of things last few years.
