Angular2 HTTP GET - Cast response into full object : <p>I have this simple Component</p>

<pre><code>import {Component} from 'angular2/core';
import {RouterLink, RouteParams} from 'angular2/router';
import {Http, Response, Headers} from 'angular2/http';
import {User} from '../../models/user';
import 'rxjs/add/operator/map';


@Component({
    template: `
        &lt;h1&gt;{{user.name}} {{user.surname}}&lt;/h1&gt;
    `,
    directives: [RouterLink],
})
export class UserComponent {

    user: User;

    constructor(private routeParams: RouteParams,
        public http: Http) {
            this.user = new User();
            this.http.get('http://localhost:3000/user/' + this.routeParams.get('id'))
                .map((res: Response) =&gt; res.json())
                .subscribe((user: User) =&gt; this.user = user);
        console.log(this.user);
    }
}
</code></pre>

<p>Why does <code>subscribe</code> not cast the response into a full <code>User</code> object. When I am logging the <code>user</code> variable my console say <code>User {_id: undefined, name: undefined, surname: undefined, email: undefined}</code>. But nevertheless binding to <code>.name</code> and <code>.surname</code> in the view is working..</p>

<p>What happens here? Where is the user actually stored? </p>
