title: reload kohana controller/action using ajax
body: <p>In Kohana 3.1 how do you use ajax (with jquery) to reload a contollers action and then update the relevent content in the view?</p>
  
  <p>e.g. I would like a controller <code>/classes/controller/user.php</code> with the action <code>public function action_bio() { ... }</code> to display a grid of 3 user avatars (user1 - user3), and fetch the user biography from db and displays it inside <code>#content</code> div of the user provided by the id parameter in the url (routed to default as user1). Each avatar is a link to the relevent user biography i.e. <code>href="/user/bio/user3"</code>.</p>
  
  <p>I would like the switching of the biography to be asynchronous so when an avatar is clicked I would like to use jquery to prevent default event and then re-run action_bio - passing it the new user id parameter. I then want to replace #content with the new biograpahy action_bio outputs.</p>
  
  <p>Thanks!</p>
