无法在popUP Leaflet Angular2中设置routerLink

Question

在我的项目中，我尝试设置popUps的链接，比如

knex seed:run

所以，问题在于此代码的第二行

ngOnInit() {
  this.ParseService.getJ().subscribe(data => {
    this.myData = JSON.parse(data);

    //set markers and popUps
    for(let i = 0; i < this.myData.length; i++) {
      let lat =+((this.myData[i])['lat']);
      let lng =+((this.myData[i])['lng']);
      this.id = (this.myData[i])['code'];
      let popUp = (this.myData[i])['displayName'] + '<br/><a [routerLink]=["/buildings", this.id] routerLinkActive="active">room</a>';
      let markerLocation = L.latLng(lat, lng);
      let marker =  new L.Marker(markerLocation, {icon: customIcon});
      map.addLayer(marker);
      marker.bindPopup(popUp);
    }
  });

如果我用

替换它

 let popUp = (this.myData[i])['displayName'] + 
'<br/><a [routerLink]=["/buildings", this.id] routerLinkActive="active">room</a>';

它有效。

问题是什么，为什么routerLink不起作用？..
