Default date

scope.form = [
  {
    "key": "birthDate",
    "minDate": "1995-09-01",
    "maxDate": new Date(),
    "format": "yyyy-mm-dd"
  }
]

above example is there any possible to pass the default today date.
like
scope.form = [
  {
    "key": "birthDate",
    "minDate": "1995-09-01",
    "maxDate": new Date(),
    "format": "yyyy-mm-dd"
   "default":new Date()
  }
]
