title: How to pass a string value to a component in angular2
body: <p>I'd like to pass a string value to a component in angular2, but it doesn't work with the default binding.
  I'm thinking of something similar to this:
  </p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;component [inputField]="string"&gt;&lt;/component&gt;
  </code></pre>
  
  <p>Unfortunately, only expressions are allowed on the right side of the assignment. Is there a way to do this?</p>
