Rails - Apr 2012 - Autocomplete text-field version of dynamic select menu?

I have a form for submission of brand, model, and style. Style
belongs_to model, and model belongs_to brand. The form is actually a
style submission form, but allows users to create new brands or models
as well, should they not exist.

What I want is for the autocomplete for ''model'' to populate
when an
object for ''brand'' is selected in the first text field..

..and so on for submodel...

I have the following autocomplete field for brand

<%= form_for @style, :html => { :class =>
''form-horizontal'' } do |f| %>
  <fieldset>
    <legend></legend>

    <div class="control-group">
      <%= f.label :brand_name, :class => ''control-label''
%>
      <div class="controls">
        <%= f.text_field :brand_name, data: {autocomplete_source:
brands_path}, :class => ''text_field''  %>
      </div>
    </div>

    <div class="form-actions">
      <%= f.submit nil, :class => ''btn btn-primary''
%>
      <%= link_to ''Cancel'', styles_path, :class =>
''btn'' %>
    </div>
  </fieldset>

<% end %>

and in styles.rb (model):

belongs_to :brand

  def brand_name
    brand.try(:name)
    end

  def brand_name=(name)
    self.brand = Brand.find_or_create_by_name(name) if name.present?
  end

and in styles.js.coffeescript:

jQuery ->
  $(''#style_brand_name'').autocomplete
    source:
$(''#style_brand_name'').data(''autocomplete-source'')
