title: Notification.alert is not working in phonegap build 3.1.0
body: <p>I am creating a phonegap application. I have used notification.alert to show messages. Before updation of phonegap 3.1.0 the notification.clert was working fine. As i have done about 5 app using phonegap 2.9.0. In every app i have used notification.alert from <a href="http://docs.phonegap.com/en/3.0.0rc1/cordova_notification_notification.md.html#Notification" rel="nofollow">this</a></p>
  
  <p>Now i have build my working project on 28th jan 2014, It is showing only 3 apps (Iphone, android and windows) can be done using phonegap. I am creating for IOS and Android. Everything is working fine except alert. Is there any problem in new phonegap? Is there any new method or command to show alert messages?</p>
  
  <p>Please help me why it is not working. If you have any other idea then please help me. </p>
