How can I have custom result with autocomplete
<%= text_field_with_auto_complete :vendor, :number, {}, {:with => "'vendor[number]=' + $('vendor_number').value"} %>

auto_complete_for :vendor, :number do |vendors, params|
  vendors.vendor_company_filter(params[:company_id])
end

def auto_complete_for_vendor_number
  @vendors = Vendor.find_by_number(number)
  render :partial => 'auto_complete_for_vendor_number'
end

<ul>
  <% @vendors. each do |vendor|  %>
    <li><%= vendor.name+'('+vendor.number+')' %></li>
  <% end %>
</ul>
