PushPlugin Not Asking for Permissions on iOS

I'm working on setting up Push Notifications for an iOS app using the Ionic Framework but I'm running into a problem.

I added the plugin using the following

ionic plugin add https://github.com/phonegap-build/PushPlugin.git

and then added the following to my services.js file:

window.onNotificationAPN = function(event){
    alert(event);
}


angular.module('starter.services', [])
.run(function($ionicPlatform){
     $ionicPlatform.ready(function($scope, $window){
        var tokenHandler = function(result){
            alert('tokenHandler' + result);
        }

        var errorHandler = function(error){
            alert('errohandler' + error);
        }

        var pushNot = window.plugins.pushNotification;
        pushNot.register(
            tokenHandler,
            errorHandler,
            {
                 "badge":"true",
                 "sound":"true",
                 "alert":"true",
                 "ecb":"onNotificationAPN"
            }
        );
    });
})

When I run the app on my test device (running iOS 6.1.6) using command+R or sending it using testflight the application runs but never asks for permission to send push notifications and the the tokenHandler function is never called. Any help would be greatly appreciated.
