title: Angular2 form: text input populates with "false"?
body: <p>I have a form to edit instances of a model (modelName). The model has a description field which is a string. The form is set up like this:</p>
  
  <pre><code>&lt;label class="form-group"&gt;
          &lt;span class="control-label col-md-3"&gt;Description&lt;/span&gt;
          &lt;span class="col-md-9"&gt;
              &lt;input class="form-control" type="text" name="description" [(ngModel)]="modelName.description" required /&gt;
          &lt;/span&gt;
  &lt;/label&gt;
  </code></pre>
  
  <p>And when the edit form is opened using an instance of the model that has a defined description, the form populates with "false" instead of the description. If I add </p>
  
  <pre><code>{{modelName.description}}
  </code></pre>
  
  <p>to the label attached to the description input, it prints the string as expected.</p>
  
  <p>I would like the form input to populate with the description string instead of "false"?</p>
