ngChange is called when model changed programmatically

Question

I have a problem when angular\'s ng-change is called when model is changed programmatically.

$scope.sendMessage = function() {
    $scope.message = \"Message sen

According to docs, you're right.

https://docs.angularjs.org/api/ng/directive/ngChange

but this seems to be a bug caused by the order in which the events are hooked up

The best way round it - with resorting to js handler (onchange)

$scope.$watch("mySelectBox", function(a,b) {
    if (a.name!=b.name) {
       $scope.message = "Message sent! (old="+b.name+', new='+a.name+')';
    }
  });
