ng-value不适用于使用ng-options选择

Question

我使用此控制器在ng-options中选择年份值：

    $http.post('http://www.lavorirapidi.it/app/include/profilo.asp?username='+username+'&id='+user_id)
    .success(function(data){
        $scope.profilo = data;
        $scope.nome = username;
        })
    .error(function(){alert("Errore di comunicazione!")});

$scope.totalyears = 100;
$scope.years = [];
var currentYear = new Date().getFullYear();
    for (var i = currentYear; i > currentYear - $scope.totalyears; i--) {
    $scope.years.push(i - 1);
    }

这是html：

        <select class="form-control" ng-model="profilo.anno" ng-options="o for o in years" ng-value="profilo.anno">
          <option value="YYYY">YYYY</option>
        </select>

但我注意到如果存在ng值（例如1999），则不会在选择菜单上设置！

问题在哪里？！

我认为我的问题在于控制器！

试试这个：link

控制器代码：

 $scope.totalyears = 100;
    $scope.profilo = {anno:2013};
    $scope.years = [];
        var currentYear = new Date().getFullYear();
        for (var i = currentYear; i > currentYear - $scope.totalyears; i--) {
        $scope.years.push(i - 1);

    }
