Ajax Pagination not working

[4x4notfound]

I've implemented ajax pagination with kaminari based on the ajax branch example and I'm getting content-type html as the response so it is rending the whole page.

The page also doesn't update with the response content.

index.html.erb

      <tbody id="foos">
        <%= render @foos %>
      </tbody>

...

    <div id="paginator">
      <%= paginate @properties, :remote => true %>
    </div>

index.js.rb

$('#foos').html('<%= escape_javascript render(@foos) %>');
$('#paginator').html('<%= escape_javascript(paginate(@foos, :remote => true).to_s) %>');

_foos.html.rb

<tr>
  <td><%= link_to image_tag(foo.bar %></td>
  <td><%= link_to foo.title, foo %></td>
  <td><%= foo.price %></td>
</tr>

foos_controller.rb

Foos.page(params[:page])
respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @foos}
end
