in_place_editor_field in Rails 2.0.2

I'm attempting to get an in_place_editor_field working in my index view. I have the following:


<% for profile in @profiles %>   <% div_for(profile) do %>   <% @profile = profile %>     <%= in_place_editor_field(:profile, :first_name) %>   <% end %> <% end %>


def index   @profiles = Profile.find(:all)

  respond_to do |format|     format.html   end end

At one point I read something about including the following line in the controller:

in_place_edit_for :profile, :first_name

However, that line doesn't do much as far as I can tell. When I go to my view, I see the text (the first name), but I cannot edit it there. I'm a bit confused as to how this is supposed to work. Any help is appreciated!
