Using Container page helper when rendering partial using AJAX

[ramsaylanier]

I'm using Browser CMS v. 3.5

I currently have a page template that initially renders a partial. On a button click, I'm replacing that partial with a different partial using ajax; however, the new partial has uses the "container" page helper. When it renders the new partial I get a "undefined method `container' " error. Below is some code:

layouts/templates/careers.html.erb

<%= render 'partials/header' %>
  <%= render 'partials/careers_header' %>    
    <div class="ajax-container">
      <div class="ajax-inner">
        <%= render 'careers/cultures' %>  #this is the initial partial in question
      </div>
    </div>


<%= render 'partials/footer' %>

config/routes.rb

...
get '/careers/:section', to: 'careers#section'
...

controllers/careers_controller.rb

class CareersController < ApplicationController

    def section
        @section = params[:section]
        respond_to do |format|
            format.js 
        end
    end
end

views/careers/section.js.erb

$('.ajax-inner').addClass('off-page');

setTimeout(function(){
    $('.ajax-inner').remove();
    $('.ajax-container').append('<div class="ajax-inner off-page"></div>');

       //renders the partial based on the instance variable passed in from the Careers controller
    $('.ajax-inner').html("<%= escape_javascript(render :partial => @section)%>"); 
}, 300);

setTimeout(function(){
    $('.ajax-inner').removeClass('off-page');
}, 600);

This all works well and good. I get a nice page transition when the content gets swapped out. However, when I try to include:

<%= container :some_container %>

i get the "undefined method `container' "

Help?
