Another way to solve this is to add .js to the form's action (if you're using a Rails link generator you can add :format => :json). Then make sure you are responding to json in your controller.

Here's an example of a sign in form configured that way:

    <%= form_for User.new, :url => session_path(:user, :format => :json), :html => {:id => "login-form", :class => "well"}, :remote => :true do |f| %>
      Email
      <%= f.text_field :email %>
      Password
      <%= f.password_field :password %>
      <%= f.hidden_field :remember_me %>
      <%= button_tag "Sign in", :class => "btn", :type => "submit" %><%= image_tag "ajax-loader.gif", :style => "display:none", :id => "login-spinner" %>
    <% end %>

In the controller:

def create
respond_to do |format|
  format.html{ super }
  format.json do
   resource = warden.authenticate!(:scope => resource_name, :recall => :failure)
   return sign_in_and_redirect(resource_name, resource)
  end
end
end
