click dispatchEvent doesn't triggers the angular 6 directive while unit testing in Jasmine/Karma

This is my directive. It is directive for the rich text which is used in the html file in the [innerHtml] field.

import { Directive, ElementRef } from '@angular/core';

import { Router } from '@angular/router';



@Directive({

  selector: '[appRichTextLink]'

})  



export class RichTextLinkDirective { 

  rawHTML: string;

  checkRouter = false;

  checkLink = false;

  constructor(public elem: ElementRef, private router: Router) {

    setTimeout(() => {

      if (this.elem.nativeElement.querySelectorAll) {

        const routerLinks: any = this.elem.nativeElement.querySelectorAll("[href]");

        const ref = this;

        if (routerLinks.length > 0) {

          for (let i = 0; i < routerLinks.length; i++) {

            routerLinks[i].addEventListener('click', function(e) {

              const hrefValue: string = this.getAttribute('href').toString();

              if (hrefValue !== "" && hrefValue !== "#" && hrefValue.indexOf('http://') === -1

                && hrefValue.indexOf('https://') === -1 && hrefValue.indexOf('//') === -1) {

                e.preventDefault();

                ref.router.navigate([hrefValue]);

              } else {

                window.open(hrefValue); 

                e.preventDefault();

                this.checkLink = true;

              }

            });

          }
