No, my code doesn't work correctly. Here is my current codee

 console.log('Before: ' + $scope.cancelLabel);
                $scope.cancelLabel = (!$scope.cancelLabel) ? $scope.cancelLabel : 'Cancel';
                console.log('After: ' + $scope.cancelLabel);

I can see that before is No and after is Cancel, so this code is not working.

How can I check for that property being set as I need to use default value for the property?
