AngularJS dropdown not showing selected value

Question

Am facing problem in displaying selected value in angular dropdown. it works when i give like this

$scope.selectedItem = $scope.items[1];

not w

Answer 1

Well, because

$scope.items[1] and { name: 'two', age: 27 } is totally different thing.

{ name: 'two', age: 27 } is a totally different object whereas $scope.items[1] is part of the object $scope.items

When you put something in the template using {{}}, angular add it in its watcher list.

SO when angular put it in the watch list, it was an object (i.e. { name: 'two', age: 27 } ) that is different than $scope.items.

selectedItem is attached with the object that you set in the controller. In summary while dirty checking, angular will checks selectedItem against { name: 'two', age: 27 } NOT against $scope.items

Hope you understand what I mean
