Offline event not triggered when turning on airplane mode

Hello everyone,

I’m trying to check the network status with the cordova-plugin-network-information plugin.

This is my actual code :

isOnline: boolean = false;

constructor(platform: Platform) {
	platform.ready().then(() => {
		document.addEventListener('offline', this.onNetworkDisconnect, false);
		document.addEventListener('online', this.onNetworkConnect, false);
	})
}

private onNetworkDisconnect(): void {
	this.isOnline = false;
	console.log('Connection lost!', this.isOnline, Network.connection);
}

private onNetworkConnect(): void {
	setTimeout(function() {
	this.isOnline = Network.connection != Connection.NONE;
	console.log('Connection restored!', this.isOnline, Network.connection);
	}, 2000);
}

I can’t figure out why but i never reach the onNetworkDisconnect() function. However when i turn airplane mode off the onNetworkConnect() works fine.

Tested on 2 different Android devices : 6.0.1 and 5.0.2 and the same problem occurs.
