title: Ionic 2 ion-datetime form binding
body: <p>I have the following:</p>
  
  <pre><code>&lt;ion-header&gt;
      &lt;ion-navbar&gt;
          &lt;button ion-button menuToggle&gt;
              &lt;ion-icon name="menu"&gt;&lt;/ion-icon&gt;
          &lt;/button&gt;
          &lt;ion-title&gt;Add new&lt;/ion-title&gt;
      &lt;/ion-navbar&gt;
  &lt;/ion-header&gt;
  
  &lt;ion-content class="ion-backdrop" padding&gt;
      &lt;form [formGroup]="form1" class="form" (ngSubmit)="onSubmit(form1.value)"&gt;
          &lt;ion-card&gt;
              &lt;ion-list&gt;
                  &lt;ion-item&gt;
                      &lt;ion-label&gt;Available:&lt;/ion-label&gt;
                      &lt;ion-datetime displayFormat="MMM DD YYYY" formControlName="dateAvailableFormControl"&gt;
                      &lt;/ion-datetime&gt;
                  &lt;/ion-item&gt;
              &lt;/ion-list&gt;
          &lt;/ion-card&gt;     
      &lt;/form&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>and my ts code is:</p>
  
  <pre><code>this.dateAvailableFormControl.setValue(this.data.DateAvailable);
  </code></pre>
  
  <p>where this.data.DateAvailable is Date type.</p>
  
  <p>I cannot see anything when page loads. All other bindings work fine except from the ion-datetime.</p>
  
  <p>Does anyone knows why this happens?</p>
  
  <p>Thanks in advance</p>
