angularfire $add not working - angularjs

Question

I'm trying to do a simple CRUD with ionic (v1) and angularfire. I can read and delete records but I need to edit and create. The actual problem is angularfire function $add`, this function doesn't do anything and doesn't return any error in the console. I have this code:
$scope.users = $firebaseArray(root.ref('/users/'));
$scope.user = {};
//Create
$scope.title = "New user"
$scope.button = "Create";
$scope.icon = "ion-person-add";
$scope.submit = function () {
var data = {
name: $scope.user.name,
username: $scope.user.username,
email: $scope.user.email,
street: $scope.user.street,
suite: $scope.user.suite,
city: $scope.user.city,
lat: $scope.user.lat,
lng: $scope.user.lng,
phone: $scope.user.phone,
website: $scope.user.website,
}
console.log(data);
$scope.users.$add(data).then(function (ref) {
console.log('contact added with Id: ' + id);;
})
Apparently the code is fine, but doesn't return console.log so maybe had some errors. Any ideas?

Answer 1

Well to find out if there is any error Javascript then takes to call back one for success and the other for failure something like the code below
$scope.user.$add(data).then(function (success){
return console.log(success);
}, function(error){
return console.log(error);
})
Now that's for then that way you can log returned errors

Error fixed.
$scope.users = $firebaseArray(root.ref('/users/'));
$scope.user = {};
//Create
$scope.title = "New user"
$scope.button = "Create";
$scope.icon = "ion-person-add";
$scope.submit = function () {
var data = {
name: $scope.user.name,
phone: $scope.user.phone,
email: $scope.user.email,
username: $scope.user.username,
city: $scope.user.city,
lat: $scope.user.lat,
lng: $scope.user.lng,
street: $scope.user.street,
suite: $scope.user.suite,
website: $scope.user.website,
zipcode: $scope.user.zipcode,
}
$scope.users.$add(data).then(function (response) {
if (response) {
$ionicPopup.alert({
title: '<div><i class="ion-checkmark-circled"></i></div>',
subTitle: '<h4>The user <b>' + data.name + '</b> is added.</h4>',
});
}
$scope.user=null;
With that all works properly and modal shows when we add user.
