Laravel, add to cart ajax(session issue)

Ajax

Hi, guys when I try to add item to EMPTY CART(empty session) asynchronously it adds the item but does not display quantity in the #counter element. But if I refresh the page the quantity appears in #counter and from there I can add items asynchronously no problems. I'm pretty sure the problem is, that session::basket variable isn't initialised for the first request. but how do I resolve it? What am I missing?

What I have tried:

controller code:

$newBasket = new Basket($previousBasket);
$newBasket->addProduct($product, $product->id);

Session::put('basket', $newBasket);
$qtny = Session::get('basket') ? Session::get('basket')->quantity : 0;
return response()->json(['added' => $qtny], 200);

$.ajax({
    type: "GET",
    url: "/product/add-to-basket/"+id,
    dataType: "json",
    data: { id: id }
  })
  .done(function(data) {
     //var ob = JSON.parse(JSON.strigify)
     $('#counter').html(data['added']);
     swal("Added to basket!");
  });
