Using Ionic Framework : @ionic/angular 4.0.0-beta.5

Ionic The ion-datetime has been binded properly to form control. But instead of a ISO-8601 format like '2017-08-21T00:00:00' it persist a object like this:

{
  "dateBk": {
    "day": { "text": "21", "value": 21, "columnIndex": 0 },
    "month": { "text": "Aug", "value": 8, "columnIndex": 1 },
    "year": { "text": "2017", "value": 2017, "columnIndex": 2 }
  }
}
