Can't bind to color since it isn't a known property of 'button'
<h2>Error</h2>

<pre><code>Can't bind to color since it isn't a known property of 'button'.
</code></pre>

<h2>Code</h2>

<pre><code>@Component({
    selector: "nav-next",
    template: `
    &lt;div class="nav-next-directive"&gt;
        &lt;button [color]="color" class="primary" [
        &lt;/button&gt;
    &lt;/div&gt;`
})
</code></pre>

<h2>Expected Behaviour</h2>

<p>This child directive enabled us in Angular2-RC4 to set colors dynamically from the parent component. Angular2-Final says this is no good. Any ideas?</p>
