Hardware back button android doesn't work after updating cordova and ionic

Since I updated Cordova and Ionic my hardware back button on Android phones doesn’t respond on the following code inside a controller:

$ionicPlatform.onHardwareBackButton(function(){
$scope.go(‘main’);
});

Cordova Version: 4.2.0
Ionic CLI: 1.3.11

I want to control the hardware back button event. Now the back button follows the screen history.
Does anyone know how to solve this? Before updating it worked.

Can somebody help me with this issue?
