Rails 3 destroy method respond_with JS using nested resources

I'm having this annoying problem with Rails 3 (ruby 1.9.2) and nested resources. In my routes:

resources :lists do
  resources :items, only: [:destroy, :update, :create]
end

My ItemsController has respond_to :json at the beginning and #destroy looks like this:

def destroy
  @item = Item.find(params[:id])
  @item.destroy
  respond_with @list, @item
end

The link to destroy the item:

<%= link_to 'x', list_item_path(@list, item), method: :delete, remote: true %>

Which translates into correct html, like:

<a href="/lists/1/items/52" data-method="delete" data-remote="true" rel="nofollow">x</a>

When I click the link, my item is correctly deleted but the method always returns {}. I've been trying to tinker with it but can't get anything different from that empty JSON object!

Every other method (#create and #update) works and returns JSON objects as expected.

I'm not entirely sure what else you would expect it to do. If the item is deleted, the JSON response will be empty since it can't return a destroyed object.

With create and update, the item object still exists so it will return that as a JSON hash.
