[angularjs] Display a angular variable in my html page

as the title says I'm trying to display an Angular variable in a html page. I have this function inside the controller I'm using :

$http.get('/api/tasks/?format=json').success(function(data) {
        $scope.tasks = data;
        for (var i=0; i < $scope.tasks.results.length; i++)
        {
            if ($scope.tasks.results.status == 0)
            {
                tobedone++;
            }
        }
    });

And now I'd like to display tobedone inside my html page. I've tried [[tobedone]] (I'm using Django, thus custom providers), but nothing displays. Any help please ?
