Hi! I want to render partial which depends on form builder “f”. How can  
I do it using AJAX+JQuery

Files  
#new.html.haml  
%h1  
New order

- form\_for(@order) do |f|  
= f.error\_messages  
%div#partial  
= render “#{@order.current\_step}\_step”, :f =\> f

#create.js.erb  
$("#partial").empty();  
$("#partial").append  
( \<%= render “#{@order.current\_step}\_step”, :locals =\> {:f=\>f}%\>);

The error  
undefined local variable or method `f’ for ActionView::Base
