Rails form not using explicit action - ruby-on-rails

Question

I'm a noob that's been struggling with this problem for longer than I care to admit. I used to have a routing issue with my STI model, but now I think that's solved (thanks to SO).
My problem is once I update the form at : /kids/1/edit, instead of having the record saved, it seems to get the record again. I know I'm missing something basic, yet after working the issue a long time the answer eludes me. You can see I'm explicitly calling the kidupdate action with the form submission.
thanks in advance.
kidedit.html.erb
<% provide(:title, "Edit user") %>
<h1>Update your profile</h1>
<div class="row">
<div class="span5 offset3">
<%= form_for(#kid, url: kidedit_path) do |f| %>
<#%= render 'shared/error_messages', object: f.object %>
<%= f.label :fname, "First Name" %>
<%= f.text_field :fname %>
<%= f.label :lname, "Last Name" %>
<%= f.text_field :lname %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.label :type, "Are you a Kid or Parent" %>
<%= f.select :type, [['Kid','Kid'],['Parent','Parent']] %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.label :password_confirmation, "Confirmation" %>
<%= f.password_field :password_confirmation %>
<%= f.submit "Save changes", class: "btn btn-large btn-primary", :controller => 'users', :action => 'kidupdate' %>
<% end %>
</div>
</div>

As the first comment said, the form should be using the update_path method:
<%= form_for(#kid, url: kidupdate_path) do |f| %>
