title: HTML date value is empty
body: <p>I bring the user birthdays from the database and reflect them on the calendar. The code part and the screenshot are as follows.
  When I say save the birthday I brought directly, it saves it blank. But it seems to be selected in the calendar because I brought it from the database. Can you help me why is this happening?</p>
  <pre><code>&lt;input type=&quot;date&quot; nbInput fullWidth fieldSize=&quot;small&quot;
   [value]=&quot;person.date| date:'yyyy-MM-dd'&quot;
  formControlName=&quot;date&quot;&gt;
  </code></pre>
