title: How to teach rails form button submit to use remote?
body: <p>The question has come up before in some postings,
  but none of them has been specific and no solution was yet proposed.</p>
  
  <p>I have a rails form.
  I use 
  I want to make this button to submit the form via ajax, aka remote:true.</p>
  
  <p>It appears to me, that rails.js does not yet honor buttons of type submit,
  it does not work for me, even if I add a data-remote tag to the button manually.
  (While it should work with )</p>
  
  <p>But I want to go the route with the new html5 button formaction attribute,
  because this makes it so much easier to assign different actions to different buttons.</p>
  
  <p>So I'm asking if I'm just missing something here,
  or if this is just plain missing from rails ujs, yet?</p>
  
  <p>I'm just digging in the rails.js now,
  so maybe someone already came up with a patch?
  to make the button type=submit remote:true work</p>
