Date picker doesn't save date.

[abalter]

When I click out of the calendar, the date goes away and isn't saved. No console errors.

I took this right from the example:

 {
    data: "startDate",
    title: "Start date",
    type: "date",
    datetimepicker: { timepicker: false, format : "Y/m/d"}
  },
