Rails 3 - AutoComplete with jQuery

Question

Hello, I'm interested in using the Rails 3 AutoComplete plugin for jQuery but the one tutorial provided doesn't match my use case. Hoping for some help...

Plug In: http://github.com/crowdint/rails3-jquery-autocomplete-app

I have a Permissions Controller where people can add team members.

On the Permissions SHOW view I want to show a autocomplete for user's....

Here's what I did: Added all the required JS in the header, loaded fine

In the permissions controller:

autocomplete :user, :name

In the config.rb:

get 'permission/autocomplete_user_name'

Then in the Permissions SHOW View

<%= form_tag do %>
<%=text_field_tag 'name', '', :autocomplete => permission_autocomplete_user_name_path %>
<% end %>

But nothing happens. No errors, and no jquery autocomplete action or activity in FireBug. Suggestions? Thank you
