How to view resource with Ajax.autocompleter

I have ajax.autocompleter working and I can get the string entered into the field from the list. But how do I view that selected text with the 'show' method? Here is my code:

----- Controller -------- def autocomplete     search = params[:user]     @users = User.find(:all,        :conditions => [ 'LOWER(first_name) LIKE ? OR LOWER(last_name)        LIKE ?',        "%#{search.downcase}%", "%#{search.downcase}%" ],        :order => 'first_name, last_name DESC',        :limit => 8) unless search.blank?     render :partial => "search"   end

------ autocompleter -------- <%= javascript_tag("new Ajax.Autocompleter('user',                           'user_results',                          '/autocomplete',                         {indicator: 'spinner',                          frequency: 0,                          minChars: 1,                         }                         );") -%>

------- search partial ---------- <ul class="autocomplete_list"> <% for user in @users do -%>   <li class="autocomplete_item">     <div class="name"><%= link_to user.whole_name, user_path(user) %></

  </li> <% end -%> </ul>

From what I've read I think I need to use the updateAfterElement

option but I don't exactly know how. When the text is selected from the list, I'd like it to invoke the 'show' medthod resulting in a url like: http://domain.com/users/1

Thanks for any help!

Oh, and I also have method: 'get' added to the autocompleter
