Control hardware back button in ionic framework

Question

i'd like to control the event of "press hardware back button" in ionic framework. This is my code. Why does not it work? thank you

.run(function ($ionicPlatform) {
        $ionicPlatform.ready(function () {
            if (window.StatusBar) {
                StatusBar.styleDefault();
            }

            $ionicPlatform.registerBackButtonAction(function (event) {
                event.preventDefault();
                event.stopPropagation();
                alert("Stop");
            }, 100);
        });
    })

i also try the other solution:

    .run(function ($ionicPlatform) {
        $ionicPlatform.ready(function () {
            if (window.StatusBar) {
                StatusBar.styleDefault();
            }
        });

        $ionicPlatform.registerBackButtonAction(function (event) {
                event.preventDefault();
                event.stopPropagation();
                alert("Stop");
            }, 100);
    })

but it still doesn't work

thank you

Answer 1

that's what you want ? :

$ionicPlatform.registerBackButtonAction(function(e){
    e.preventDefault();
    return false;
}, 101);
