The problem is that your request is not resolved at the moment when you're checking it. You need to use Promise callback to assign loaded data to a scope variable.

ZustShopController.controller("ProductController",function($rootScope,$scope,DecreaseQuantitytService){
  DecreaseQuantitytService.DecreseQuantiyItem(item).then(function(data){
    $scope.itemslist = data;
  }
})

and so? AJAX call being async, whatever it's wrapped into needs a callback wrapper on some level service or controller - which I don't see in your code example
