title: Angular 4 subscribe not working in lazyload
body: <p>using this example: <a href="https://hassantariqblog.wordpress.com/2016/12/03/angular2-using-loaderspinner-as-angular-service-in-angular-2-application/" rel="nofollow noreferrer">enter link description here</a></p>
  
  <p>everything works perfect - until I make the component a lazyload component, then the loader stops appearing.
  any idea what I'm missing here?</p>
