Update item on TodoList Angularfire

Using Angularfire, i create todoList. But i have a problem in updating items. I try this code

 var obj = $firebaseObject(ref);
 obj.name = $scope.todo.title ;
 obj.$save()
  .then(function(ref) {
    ref.key() === obj.$id; // true
  }, function(error) {
    console.log("Error:", error);
  });

How can i update only the selected item.

Note that you can also simply update the TODO item's title directly, without going through $firebaseObject():

ref.update({ title: $scope.todo.title });

The $firebaseObject() and $firebaseArray() services are great for binding the underlying data to Angular views, but to perform an update to the data you can just as easily take the more direct approach. Since AngularFire is built on top of the Firebase JavaScript SDK, they interoperate perfectly.

How about this?

var obj = $firebaseObject(ref);
obj.$loaded().then(function () {
    obj.name = $scope.todo.title;
    obj.$save()
        .then(function (ref) {
            ref.key() === obj.$id; // true
        }, function (error) {
            console.log("Error:", error);
        });
});

You are trying to save it before it's been loaded.
