TypeScript InversifyJS: asynchronous binding - asynchronous

Question

I'm facing this kind of problem: I'm creating Event Manager with ability to handle several concrete providers, and I'm struggling with dependency injection issue here.
I'm using:
Typescript#2.0.10, node#7.0.0, inversify#2.0.1, inversify-binding-decorators#2.0.0
Lets see that in code:
const socketIO: SocketIO.Server = io.listen(instance);
kernel.bind<SocketIO.Server>(TYPES.SocketIO).toConstantValue(socketIO);
const eventManager: IEventManager = kernel.get<IEventManager>(TYPES.IEventManager);
eventManager.init(kernel.getAll<IEventManagerProvider>(TYPES.IEventManagerProvider));
console.log(eventManager);
And console logs me that event manager is undefined, which crashes the whole app. But...
When I disable the kernel.getAll(...) from init, then I'm receiving just what I've expected:
const eventManager: IEventManager = kernel.get<IEventManager>(TYPES.IEventManager);
eventManager.init([]);
console.log(eventManager);
Gives me: MultipleProvidersEventManager { providers: {} }. The init method is very simple by itself and contains:
#provideSingleton(TYPES.IEventManager)
class MultipleProvidersEventManager {
...
public init(providers: IEventManagerProvider[]): void {
forEach(providers, this.registerProvider);
}
public registerProvider(provider: IEventManagerProvider): void {
if (this.providers[provider.type()]) {
throw new Error('Event Manager provider already registered');
}
console.log('Registered ' + provider.type() + ' event manager provider');
this.providers[provider.type()] = provider;
}
...
}
So my problem is that I have to wait with calling the init method until
all required objects are stored properly in InversifyJS container and can be returned. But I don't know how :(. Can someone explain me how should I solve this problem ?

Ok, I've solve it.
The problem was in totally different place that I was thinking on the beginning.
So... in MultipleProvidersEventManager class on init method, forEach was loosing the context of the caller. Adding bind soved the problem..
forEach(providers, this.registerProvider.bind(this));
... is the anwser.
