Angular2 component rendering with javascript inside

Question

First of all, I am very new to Angular2 (or any other version actually) and I have followed several tutorials to get me started but I'm now in a dead end and I don't know how to proceed. Here is the background: I am accessing a third party web API through a POST request (I did that in a service) and it returns HTML markup of the control I need to render on my page, so I made a component of it. It works fine (I had to create a custom pipe to work around the DOM sanitization though).

And here's my issue: in the markup I'm receiving from the web API there's JavaScript stuff to initialize the control that is supposed to execute as soon as it is on the page (it does in every other language I used this control in, PHP, Java, JavaScript, ASP.NET, etc) but for some reason, using Angular2 I can see the script in the DOM, properly inserted at the end of the markup but it does not execute so my control does not work.

Here is my component code:

import { Component, OnInit, ViewEncapsulation } from '@angular/core';

import { MyService } from './my.service'

@Component({
    selector: 'mycontrol',
    template: `<div style="width:1200px; height:1000px;" [innerHtml]="htmlContent | keepHtml"></div>`,
    styleUrls: ['app/control-min.css'],
    encapsulation: ViewEncapsulation.None
})

export class MyComponent implements OnInit {
    htmlContent: any;

    constructor(private myService: MyService) {
    }

    ngOnInit(): void {
        this.myService.getControlMarkup().subscribe(
            response => this.htmlContent = response["HtmlContent"],
            error => this.htmlContent = <any>error
        );
    }
}

And here is my service code:

import { Injectable } from '@angular/core';
import { Http, Response, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/Rx';

@Injectable()
export class MyService {
    headers: Headers;
    options: RequestOptions;

    constructor(private http: Http) {
        this.headers = new Headers({ 'Content-Type': 'application/json' });
        this.options = new RequestOptions({ headers: this.headers });
    }

    getControlMarkup() {
        let controlConfig = {
            SessionId: "mySessionId",
            ControlId: "MyControl1"
        };
        let body = JSON.stringify(controlConfig);
        return this.http
            .post('http://localhost:62968/api/GetControl', body, this.options)
            .map(this.extractData)
            .catch(this.handleError);
    }

    private extractData(res: Response) {
        let body = res.json();
        return body || {};
    }

    private handleError(error: any) {
        let errMsg = (error.message) ? error.message : error.status ? `${error.status} - ${error.statusText}` : 'Server error';
        console.error(errMsg);
        return Observable.throw(errMsg);
    }
}

Any idea how I can make this work?
