Update method is passing id in a weird way

Somehow, my update method after editing is passing the id as "show"

here is a look at the parameters being passed when I "update"\

My form is, which is the same form for new owner (and works):

<%=form_for @owner , remote: true do |f| %>

    </div>

    <div class="modal-footer">

                <%= link_to "Cancel", "#", class: "btn", data: {dismiss: "modal"} %>
    </div>

the update.html.erb renders the same save.js.erb which works find when creating a new Owner.
