HI im trying to make a Datatype with a dataview. A Textarea is used to display Json.

i have a temp $scope.model.Json

$scope.model.Json = JSON.stringify($scope.model.value.Json, undefined, 2);

which is parsed to the original value with JSlint

$scope.model.value.Json = jsonlint.parse($scope.model.Json);

Now if the $scope.model.value.Json is undefined i cant get the scope to update... how do i force this value to update??

i tryied to assign it but it does not update

 if ($scope.model.value.Json === undefined) {
            console.log("default value");
            $scope.model.value.Json = {};
        } else {
            $scope.model.Json = JSON.stringify($scope.model.value.Json, undefined, 2);
        }
