title: data-remote true defining a callback
body: <p>I have a form that I would like to submit with the <code>data-remote=true</code> option.  But I want to have my create action return json, then have that handled by javascript that already exists on the page.  Can I set a callback inline with the form_for tag?</p>
  
  <p>Something similar to this:</p>
  
  <pre><code>=form_for @foo,:remote =&gt; true, :success =&gt; "my_js_stuff" do |f|
  </code></pre>
