CSRF protection not working with jquery ajax post request

Rails
1

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
