how to call controller action in ajax url

Question

I want to call the controller method in ajax url to dynamically populate the dropdown based on value from another dropdown. The value I am getting is string, when I call this method using ajax url it always refers to 'show' method. My ajax call

$('#users').change(function() {
  url: '/users/update_groups',
  data: {name: $(this).val()},
  success: function (data) {
    alert(data);
  }
});

In my users_controller.rb

def update_groups user_name
  # returns list of groups
end

How to call this method using ajax url?

      alert(data);
