how i opposite rjs templates same rails controller?

i have controller slight advantage list dump down gets rendered partial, nonetheless depending where biased being used, rjs template needs different. i pass parameter controller establish rjs gets used?

here controller method, unequivocally simple:

def services
   respond_to |format|
     format.js {
       @type     = hospitalcriteria.find_by_id(params[:type_id])
       @services = @type.children.all
     }
   end
end

and here rjs template gets rendered automatically

page.replace_html 'select_service', :partial => 'hospital/services'
page.replace_html 'select_condition', :partial => 'hospital/conditions'
page.replace_html 'select_procedure', :partial => 'hospital/procedures'

page << 'if ($("chosentype") != null) {'
  page.replace_html 'chosentype', @type.name
  page.replace_html 'chosenservice', 'selected service'
  page.replace_html 'chosencondition', 'selected condition'
  page.replace_html 'chosenprocedure', 'selected procedure'
page << '}'
