Property 'getPermissionSubscriptionState' does not exists on type 'OneSignal'

[AntonioMenti]

Good Morning,

i've created an ionic 3 app with One Signal. Notification correctly received but i can't access getPermissionSubscriptionState method.

ionic info tell me that i have the latest version installed.
Costructor

private _SIGNAL : OneSignal

and then:
this._SIGNAL.getPermissionSubscriptionState() .then((msg) { console.log(JSON.stringify(msg)); });

ionic info command:

`global packages:

@ionic/cli-utils : 1.4.0
Cordova CLI      : 6.5.0
Ionic CLI        : 3.4.0

local packages:

@ionic/app-scripts              : 1.3.7
@ionic/cli-plugin-cordova       : 1.4.0
@ionic/cli-plugin-ionic-angular : 1.3.1
Cordova Platforms               : android 6.1.2
Ionic Framework                 : ionic-angular 3.4.2

System:

Node       : v6.7.0
OS         : Windows 7
Xcode      : not installed
ios-deploy : not installed
ios-sim    : not installed
npm        : 3.10.3`

Any ideas? What's i'm wrong?
