Аякс не видит функцию?

Question

Существует CBV (JointProductsDetail), который отвечает за рендеринг шаблона.В шаблоне я пытаюсь выполнить запрос ajax (тип get).Я указываю url.Запрос не приходит к указанной функции, но я получаю success в ответе.

template

<form>
  <a href='#' class='add_to_cart'>
    <button class='btn btn-danger' id="make_an_order" type="button">abc</button>
  </a>
</form>

<script>
$(document).ready(function(){
  $('.add_to_cart').on('click', function(e){
    $.ajax({
      type: "GET",
      url: "{% url 'add_to_cart' %}",
      data: {},
      success: function(data){
        alert('Товар добавлен в корзину');
        location.reload();
      },
      error: function(data){
        alert('Произошла ошибка. Попробуйте позже')
      }
    })
  })
})
</script>
