Angular - ng-change not firing when ng-model is changed

javascript angularjs data-binding angular-ngmodel angularjs-ng-change

ngChange is just for the input, if you want to listen the model do like this

$scope.$watch('repair.test', function(newvalue,oldvalue) {            });

javascript angularjs data-binding angular-ngmodel angularjs-ng-change

The ngChange expression is only evaluated when a change in the input value causes a new value to be committed to the model.

It will not be evaluated:

if the value returned from the $parsers transformation pipeline hasnot changed
if the input has continued to be invalid since the modelwill stay null
if the model is changed programmatically and not by achange to the input value

Try to create a watcher using $scope.$watch - $watch(watchExpression, listener, [objectEquality]);

Example

$scope.$watch('repair.test', function(newValue, oldValue) {    // ...});

You can use a watcher-function in your controller

$scope.$watch('repair.test', function() {    $scope.action();});
