Create a new instance of a class that is using dependency injection in Aurelia

I want to create a factory that is able to create a new instance of a class (MyClass, implementing an abstract class) that is using dependency injection.

I would like the factory to look like this:

Factory

export class Factory {

  public static makeMyClass() {
    return new MyClass();
  }

}

However, the EventAggregator is not injected into MyClass when I take this approach.

How can I do this?

Interface

export abstract class MyClassInterface {

  abstract connect();
  abstract disconnect();
  abstract send(message: string);

}

Class

@inject(EventAggregator)
export class MyClass {

  constructor(EventAggregator) {}

  connect() {}
  disconnect() {}
  send(message: string) {}

}

Thanks in advance!
