How to perform a check on ng-disabled in angularjs?

I guess AngularJS cannot check if the output of canMoveForward() has changed or not. I found that for this kind of things it's easier to rely on scope variables. You could do something like this:

ng-disabled="!canMoveForward"

Then in your controller just set the property to true/false as needed:

$scope.canMoveForward = false;

I have had the same problem and I've discovered that the problem is with the ! operator.

This fails:

ng-disabled="!canMoveForward()"

But this will work:

ng-disabled="canNotMoveForward()"
