Angular 2 http.post() is not sending the request : <p>When I make a post request the angular 2 http is not sending this request</p>

<pre><code>this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions())
</code></pre>

<p>the http post is not sent to the server but if I make the request like this </p>

<pre><code>this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions()).subscribe(r=&gt;{});
</code></pre>

<p>Is this intended and if it is can someone explain me why ? Or it is a bug ?</p>
