CSRF protection not working with jquery ajax post request

Hallo, I want to test the csrf protection of my application but forgery protection is not working with jquery ajax request. I have used Unobtrusive Javascript with jquery I have removed the <%= csrf_meta_tag %> so that my application do not include authenticity token. In my view I have the following code

$(function () {    $('#alert').click(function () {          $.ajax({           type: "POST",           data: ({ lo: 67, pi: 22 }),           url: '/test/set',

        });     }) });

I have also include in the application controller protect_from_forgery

and have set in development configuration config.action_controller.consider_all_requests_local = false

However the post command is completed successfully. Does anyone know why the protection is not working?

Thank you
