angular2 onError image binding

I'm wondering if we can bind or interpolate the onError on the image tag using angular2,

on the app.component.ts:

imageUrl:string;

  constructor( ) {
      this.imageUrl = 'graphics/placeholder.gif';
   }

on the app.component.html:

<img class="img-responsive" [src]="'graphics/image-1.jpg'" onError="imageUrl"/>

The method below works.

<img class="img-responsive" [src]="'graphics/image-1.jpg'" onError="this.src='graphics/placeholder.gif'"/>

But as we using a many images on the app and I would like to make it a simple dynamic solution, I found this answer as well,

Angular 2 - Check if image url is valid or broken

but for some reason is not working, I don't know what I'm doing wrong here

It was almost complete he just forgot to change the image after the event.

errorHandler(event) {
   console.debug(event);
   event.target.src = "https://cdn.browshot.com/static/images/not-found.png";
}

Here is the link

component.ts

onImgError(event){
 event.target.src = './assets/imgs/altImg.png'
//Do other stuff with the event.target
}

component.html

 <img [src]="imgUrl" (error)="onImgError($event)">
