ngCordova Datepicker doest not show in iOS 9.1 in a .ipa app

I have used Ionic Package to create .ipa file and installed in the iPhone iOS 9.1 but this Cordova datepicker plugin
does not show up, also the Toast plug in
does not work.
Both these plugins work in the iOS 9.1 Simulator via Ionic Emulate and xCode 7.1.1
I am using ionicplatformready as per below
$ionicPlatform.ready(function() {
$scope.addmatch.matchdate = date;

any help on this would be greatly appreciated.
