Я создаю веб-приложение с Rails 5, и у меня есть проблема с удаленными формами в AJAX

Моя проблема в типе данных, которые отправляются на сервер, не распознает данные функции браузера

_form.html.erb 

<br>
   <%=form_for([@article,@comment], remote: true, html: { id: "comments-form", :"data-type" => "json" }) do |form| %>
</br>

comments.coffee

$(document).on "ajax:success", "form#comments-form", (ev,data)->
  console.log data

ответ браузера 

(function() {
  $(document).on("ajax:success", "form#comments-form", function(ev, data) 
  {});
  console.log(data);
}).call(this);

Ошибка в консоли

Uncaught ReferenceError: data is not defined
