Phonegap events online/offline not working

Question

I am writing app with phonegap(cordova) 3.0.0 and events "online" and "offline" doesn't work. When I tried event "resume", this event was OK. I am using XCode 4.5 and IOS.

This is my main javascript file of phonegap project:

var app = {

    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:
    // 'load', 'deviceready', 'offline', and 'online'.
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
        document.addEventListener('online', this.onDeviceOnline, false);
        document.addEventListener('resume', this.onDeviceResume, false);
    },

    onDeviceReady: function() {
        app.receivedEvent('deviceready');
    },

    onDeviceOnline: function() {
        app.receivedEvent('deviceonline');
    },

    onDeviceResume: function() {
        app.receivedEvent('deviceresume');
    },

    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }
};

Thank for advices

if you want to display online / offline status you need to add network-information plugin first with command prompt

$ phonegap local plugin add org.apache.cordova.network-information

after adding that plugin your online / offline event should work, it work fine for me
