Hi @bilalbash I suppose that a CSRF token is not sent in ajax requests.

Let me know what will happen when you add the following line in application.js.

app/assets/javascripts/application.js

//= require jquery
//= require jquery_ujs <--- Add this line

[bilalbash]

yes it fixed the issue

I updated the README. Thank you.
