I want to use @hostListner on div to execute a method when div is loaded:

<div id="content">
<router-outlet ></router-outlet>
</div>

in my app.ts I do:

  @HostListener('window:load',['$event'])
  onPageLoad(event: Event) {
     console.log('loaded',event); }

I don't want how listener is called on 'window:load'. I want call somethink like this

 @HostListener('content:load',['$event'])
  onPageLoad(event: Event) {
     console.log('loaded',event); }

I don't know if I can do this. Anyone can help me?
