Recursive Angular 2 HTML Binding

Question

Here is my problem, I want to include a button inside an HTML template that links to an external website. But when the HTML is being read, Google Chrome says:

WARNING: sanitizing HTML stripped some content (see http://g.co/ng/security#xss).

It seems that the Angular 2 innerHTML attribute does not allow the use of 2 recursive HTML bindings.

Here is my code:

<ion-col width-80 innerHtml="{{ slide.content + '<p><button round full (click)=`' 
+ slide.button.url +'`>'+slide.button.text+'</button>' }}"></ion-col>

The attribute (click) is deleted, and only (slide.button.text)displayed as separate text.

Any solution?

slide as follows:

{
    img: 'img/picture.png',
    content: `sometext`,
    button : {
        url: `http://www.foo.com`,
        text: `Site foo`
    }
}

NOTE. I don’t know ion, so I changed it to HTML control. changed buttonto a (link).

//our root app component
import {Component, Pipe} from '@angular/core'
import {DomSanitizationService} from '@angular/platform-browser';

@Component({
  selector: 'my-app',

  template: `
    <span [innerHTML]="myHTML"></span>

})

export class AppComponent {
  slide={

    content: `sometext`,
    button : {
        url: `http://www.foo.com`,
        text: `Site foo`
    }
  };

  dangerousUrl='<p><a href='+`${this.slide.button.url}`+'>'+`${this.slide.button.text}`+'</a></p>';

  constructor(sanitizer: DomSanitizationService) {
       this.myHTML= sanitizer.bypassSecurityTrustHtml(this.dangerousUrl);
  }
}
