title: Call controller and reload partials
body: <p>I have a page that renders multiple partials, including a Flash div that takes a while to start up.  </p>
  
  <p>I have a button that I want to re-hit the controller, pull down any new data, and reload all the partials in the page except for the Flash div.</p>
  
  <p>I've looked into rjs, but it seems like you need to add another route and controller method to accomplish this.  Is there a way to keep all the logic contained in the same page?</p>
