javascript - After ajax google analytics tag not working

Solution:

You shouldn't send transaction information with add to cart event. To measure the addition of a product to a shopping cart, send an add_to_cart event with the product information:

gtag('event', 'add_to_cart', {
  "items": [
    {
      "id": "P12345",
      "name": "Android Warhol T-Shirt",
      "list_name": "Search Results",
      "brand": "Google",
      "category": "Apparel/T-Shirts",
      "variant": "Black",
      "list_position": 1,
      "quantity": 2,
      "price": '2.0'
    }
  ]
});

   function gtag(){dataLayer.push(arguments);}
   gtag('js', new Date());

   gtag('event', 'purchase', {
        "transaction_id": response.SiparisNumarasi,
        "affiliation": "Marketcimrisi",
        "value":response.OdenenTutar,
        "currency": "TRY",
        "tax": 0,
