You'll want to add something like the following:
respond_to do |format|
format.js { render :create1 }
end
Alternately, if you had a different path to it besides the default you could use:
format.js { render :file => "/path/to/save.js.erb" }
If it is a more dynamic requirement than this, you could always use string interpolation or "string".to_sym to render the desired view.
