List and detail item ionic

I have a problem , I can not load the data of the item called because the database queries defined in services.js runs after and so my array is empty when called by $ brooms , someone has a solution I have to run the query inside the controller itself?

thanks in advance

controller('SchedaProdottoCtrl', function(ProductService, $cordovaSQLite, $scope,$stateParams, $ionicLoading,               $ionicActionSheet, $ionicListDelegate, GetTodayDate) {

    $scope.items = ProductService.get($stateParams.productID);

});

And in the services.js have:

.factory('ProductService', function($cordovaSQLite) {

   var items = [];
    $cordovaSQLite.execute(db, "SELECT * FROM prodotti").then(function(res) {
        if (res.rows.length) {
            for (var i = 0; i < res.rows.length; i++) {
            var row = res.rows.item(i);
                 items.push({
                     IdProdotti:row.idProdotti,
                     nomeProdotto:row.Nome,
                     dataScadenza:row.DataScadenza
                });
            }
        } else {
            console.log('No result found');
        return false;
        }
});


return {
all: function() {
  return items;
},
get: function(productID) {
  // Simple index lookup
  return items[productID];
}
}
})
