A more successful way to implement the addEventListener function for Multiple events bindings.

add_event_listener_using_this_dot_manager.ts

  addEventListener(element: HTMLElement, eventName: string, handler: Function): Function {
    var zone = this.manager.getZone();
    var eventsArray = this.getMultiEventArray(eventName);

    // Entering back into angular to trigger changeDetection
    var outsideHandler = (event) => {
        zone.run(() => handler(event))
    };

    // Executed outside of angular so that change detection is not constantly triggered.
    var addAndRemoveHostListenersForOutsideEvents = () => {
      eventsArray.forEach((singleEventName: string) => {
        // Sending the events back up to this.manager allows the events to be handled by the appropriate plugin
        this.manager.addEventListener(element, singleEventName, outsideHandler);
      });
    }

    return this.manager.getZone().runOutsideAngular(addAndRemoveHostListenersForOutsideEvents);
  }
