You can do this with jQuery. I think the best way to do this (I think) is to have a method in your controller that do nothing but a findAll() on your Demands repo :

public function demandsAction()
{
    $entity = $em->getRepository('PublishDemandsBundle:Demands')->findAll();

    return $this->render('PublishDemandsBundle:Demands:liste.html.twig', array(
       'entity' => $entity
        ));
}

Make sure this Action can be called by a route, let's say /ajax/demands/ Then, in your twig template, just do :

 <div id="demands">
      {{ render(controller("PublishDemandsBundle:MainController:demands")) }}
 </div>
 <a href="#" id="reload">reload</a>

With a bit of jQuery :

 $('#reload').click(function() {
     $.get("/ajax/demands", function( data ) {
     $('#demands').html( data );
 });

I haven't tested this yet, and it might be adapted to your case, but again, I would do it this way.
