"respond_with" not working Rails 3

As no one can help me with my UJS ajax problem I am trying "respond_with", but I am getting this error:- RuntimeError (In order to use respond_with, first you need to declare the formats your controller responds to in the class level):

Yet I have declared it in my controller:-

class HomepagesController < ApplicationController     respond_to :html, :xml, :js

   def index     @homepages = Homepage.search(params[:search])     respond_with(@homepages)     end

Anyone has any ideas why.

A certain Javix suggested:-   I think, may be I'm wrong, - the problem is how you defined it in your routes.rb file. If you defined homepages as

  resources :homepages

  Rails will try to match that resource to any non-XHR (not Ajax request) for action 'index'; If it's true, I think you will have to redefine resources for homepages.

I have not heard of this can anyone shed some light for me please.
