backgroundgeolocation plugin + phonegap developer app does not work

I`m using Ionic as a mobile app and testing my things in combination with the phonegap developer app.

I always get an 'undefined' for the backgroundgeolocation plugin when using phonegap developer app and executing 'phonegap serve'

I've added the cordova plugin:

cordova plugin add https://github.com/christocracy/cordova-plugin-background-geolocation.git

I adapted config.xml and included the plugin.

<gap:plugin name="org.transistorsoft.cordova.background-geolocation" />

How do I use the backgroundgeolocation plugin in combination with the 'phonegap serve' command?

This is what I tried:

.controller('DashCtrl', function($scope,$cordovaBackgroundGeolocation,$ionicPlatform,$cordovaGeolocation,$window,$timeout) {
    document.addEventListener("deviceready", function () {
        $ionicPlatform.ready(function() {
            $window.navigator.geolocation.getCurrentPosition(function(location) {
                console.log('Location from Phonegap');
            });
            $timeout(function() {
                var bgGeo = $window.plugins.backgroundGeoLocation;
                alert(bgGeo);
                var callbackFn = function(location){
                    alert('YEEEAH'+JSON.stringify(location));
                };
                var failureFn = function(error){
                    alert('Geolocation Error');
                };
                bgGeo.configure(callbackFn, failureFn, {
                    desiredAccuracy: 0,
                    stationaryRadius: 5,
                    distanceFilter: 30,
                    debug: true
                });
                alert('start');
                bgGeo.start();
                alert('started');
            },5000);
        });
    }, false);
});
