调用Ionic 1 cordova inAppBrowser事件未在打开后触发

Question

我正在编写一些在AppBrowser中打开的代码，客户端可以在我的网站上完成某些操作，然后从我的应用程序中收听事件并在完成后关闭浏览器。但是在调用open之后，下面的所有其他代码行都不会被调用。

   var options = {
        location: 'yes',
        clearcache: 'no',
        toolbar: 'no'
    },
    url=appConfig.appUrl + '/premium/'+$scope.videoData.slug+'/payment';
    $ionicLoading.show();
    $cordovaInAppBrowser.open(url, '_blank', options).catch(function() {
            $scope.showAlert('Error', 'There was an error reaching the server');
        });
    //below here never executes
    $rootScope.$on('$cordovaInAppBrowser:loadstop', function(e, event){
        alert('mr');
        var loc = event.url;
        console.log(e, event);
        //when url is changed check if the url contains your specific callbackURL
        if (loc.indexOf('successfuls') >= 0) {
        //at this point close your inapp browser
        //you will land on the index page within your application.
            $cordovaInAppBrowser.close();
            $ionicLoading.hide();
            $scope.showAlert('Successfull!', 'You successfully purc+hased download for this video!');
            $scope.is_expired = false;
            $scope.is_video   = true;   
            $scope.time_diff = +$scope.videoData.premium_duration * 3600;
        }

        if(loc.indexOf('failed') >=0){
                $cordovaInAppBrowser.close();
                $ionicLoading.hide();
                $scope.showAlert('Alert', 'Could not process payment!')
        }
    });`

任何人都知道为什么会发生这种情况，检查浏览器和设备上的行为会产生相同的结果。
