Rendering partial views with ajax calls in rails 3.1

Hi, i’m starting now with rails, and i have simply question.
I need to render two partials in one ajax call:

I have the following controller:

GET /hosts/1

GET /hosts/1.json

def show
@host = Host.find(params[:id])

respond_to do |format|
format.html #show.html
format.json { render :json => @host }

And the respective template (show.js.erb):

$(’#tabs-1’).html("<%= escape_javascript(render @host) %>");

And a partial file named _host.html.erb

All this works fine, but now i need to add some other partial template
in a different id (#tabs-2), but use the same @host
How can i do this? de default render @host will use the template file
_host.html.erb. How can i call a different one like _host2.html.erb and
have the same @host instance?
