How do I render partial via ajax in rails3 and jQuery

I could do sth like this in rails 2:

def show_rec_horses
  rec_horses = Horses.find(:all)
  page["allHorses"].replace_html :partial => "horses/recommended", :locals => 
 {:rec_horses => rec_horses}
end

How do I do this in Rails3 with jQuery. So how can I replace html of my div with a partial via ajax call(link_to :remote => true) in Rails3.

I tried sth like (in my show_rec_horses.js.erb):

$("#interactionContainer").update("<%= escape_javascript(render("horses/recommended"))%>");

And nothing happens. I tried some other variations but none worked. What am doing wrong? Should this be approached in some other way? Any answer would be greatly appreciated.
