phonegap build:Not getting registration Id on iOS 9.1 push notification - push-notification

Question

I am trying to build a simple app using latest pushnotification plugin. I am using Phonegap build. But I am not able to get the registration Id on iOS 9.1 but it is working on iOS8. Check below code
var push = PushNotification.init({
"android": {
"senderID": "12345679"
},"ios": {
"alert": "true", "badge": "true", "sound": "true"
}, "windows": { }
});
push.on('registration', function(data) {
alert("got registration id");
console.log(JSON.stringify(data));
localStorage.setItem("deviceToken", data.registrationId);
});
push.on('notification', function(data) {
// data.message,
// data.title,
// data.count,
// data.sound,
// data.image,
// data.additionalData
});
push.on('error', function(e) {
// e.message
alert(e.message);
});
Config.xml
<gap:plugin name="phonegap-plugin-push" source="npm" version="1.4.2" />
<preference name="phonegap-version" value="cli-5.2.0" />
<preference name="android-build-tool" value="gradle"/>

I found the solution of this problem,
Actually it's not certain thing but it's combination of more than one factor
For client side make sure to use the latest version of the push plugin found here which is 1.4.2 (till now)
here is the a sample of client side code
var push = PushNotification.init({ "android": {"senderID": "12345679"},
"ios": {"alert": "true", "badge": "true", "sound": "true"}, "windows": {} } );
push.on('registration', function(data) {
// data.registrationId
});
push.on('notification', function(data) {
// data.message,
// data.title,
// data.count,
// data.sound,
// data.image,
// data.additionalData
});
push.on('error', function(e) {
// e.message
});
For server side and Xcode project :
1- be sure to use Xcode 7.1.1 (latest stable version till now)
2- be sure to create APNS Production NOT DEVELOPMENT certificate then download it
3- drag it or open it with keychain access expand it and export the private key as yourAppNameKey.p12
4- then we need to generate the pem file for the certificate,So via terminal write :
openssl x509 -in aps_production.cer -inform der -out yourAppNameCert.pem
Note : ins the last step we used the certificate which we downloaded in step 2
5- now we will Convert the private key’s .p12 file into a .pem file:
openssl pkcs12 -nocerts -out yourAppNameKey.pem -in yourAppNameKey.p12
Note : you will be asked to enter the password you used to export the private key and insert a pass phrase and confirm it to use in the server side code
6 - Finally we will combine the certificate and key into a single .pem file:
cat PushChatCert.pem PushChatKey.pem > ck.pem
here is a sample of the server side code
Hope it works with everyone .. Thanks
