Angular2 : two way binding inside parent/child component : <p>Version: "angular2": "2.0.0-beta.6"</p>

<p>I would like to implement a two way binding inside a parent/child component case.</p>

<p>On my child component, I'm using two-way binding to display text while editing.</p>

<p>Child component (<code>InputTestComponent [selector:'input-test']</code>):</p>

<pre><code>&lt;form (ngSubmit)="onSubmit()" #testform="ngForm"&gt;
    {{name}}
    &lt;textarea #textarea [(ngModel)]="name" ngControl="name" name="name"&gt;&lt;/textarea&gt;
    &lt;button type="submit"&gt;Go&lt;/button&gt;
&lt;/form&gt;
</code></pre>

<p>Then, I would like to propagate this change to his parent component.
I tried with <code>[(name)]="name"</code> with no success.</p>

<p>Parent component:</p>

<pre><code>&lt;div&gt;
  {{name}}
  &lt;input-test [(name)]="name"&gt;&lt;/input-test&gt;
&lt;/div&gt;
</code></pre>

<p>What the easiest way to do it (less verbose) ?</p>
