Current behavior When used in inside a component with changeDetection: ChangeDetectionStrategy.OnPush loading bar does not work.

Reproduction of the problem Place <ng2-slim-loading-bar></ng2-slim-loading-bar> inside a template of a component with changeDetection: ChangeDetectionStrategy.OnPush. Try start() - progress is updated, but component view is not reflecting that.

What is the expected behavior? SlimLoadingBarComponent component should have changeDetection: ChangeDetectionStrategy.OnPush. It needs to inject private cd: ChangeDetectorRef and at the end of this.service.events.subscribe it should call this.cd.markForCheck();

What is the motivation / use case for changing the behavior? This makes the component usable when changeDetection: ChangeDetectionStrategy.OnPush is used. Note that with redux/ngrx this change detection is very common.

Please tell us about your environment:

• ng2-slim-loading-bar version: 4.0.0

• Angular version: 4.0.1

• Browser: all

• Language: all
