I can probs tackle this with the approach taken in bentranter/turbolinks, though it's still missing support for some of the rails-ujs features. I'll look into this over the next few days.

@bentranter Thanks Ben! Some of the Rails UJS stuff is handled because Lucky is bundled with the Rails UJS npm package. So you can do data_remote: true on a form and it submits with AJAX. So I think it just needs the turbolinks specific stuff like you did in your Turbolinks handler
