我有一个带文本区域的ionicPopup，当用户输入文本时，保存在firebase中。在这个值的改变上，我能够在移动设备上触发ngCordova本地通知谁的用户已经输入了数据。我如何让这个值更改在每个登录用户的手机上触发相同的通知。

服务：

servicesModule.factory("Profile", ["$firebaseObject",
  function($firebaseObject) {
    return function(new_value) {
      var ref = new Firebase("https://feedback-system.firebaseio.com/Courses/" + 'newValue');
      var new_value_ref = ref.child(new_value);
      return $firebaseObject(new_value_ref);
    }
  }
]);

控制器：

var ionicApp = angular.module('localNotificationModule', ['ionic', 'ngCordova']);
ionicApp.controller('localNotificationCtrl', ['$scope', '$rootScope', '$ionicPlatform', '$cordovaLocalNotification', '$state', 'Profile', '$firebase', 'Firebase', function($scope, $rootScope, $ionicPlatform, $cordovaLocalNotification, $state, Profile, $firebase, Firebase){
        $scope.profile = Profile("physicsmarie");
        // calling $save() on the synchronized object syncs all data back to our Firebase database
        $scope.testNotification = function() {
          $scope.profile.$save().then(function() {
            scheduleDelayedNotification($scope.profile.name);
          }).catch(function(error) {
            alert('Error!');
          });
        };
function scheduleDelayedNotification(newValue) {
    $ionicPlatform.ready(function () {
            $cordovaLocalNotification.schedule({
                id: 1,
                title: 'New Notification',
                text: newValue,
                autoCancel: true
            }).then(function (result) {
                alert("Notification Set");
            });
    });
    };
}]);
