Get value back from umb-editor

Questions
1

Hi, I’m trying to reuse the umb-editor directive with datepicker view:

controller:

$scope.myvalue = {}; 

$scope.datepickerModel = {
  alias: 'mydatepicker',
  view: 'datepicker',
  value: $scope.myvalue,
  config: {
    pickDate: true,
    pickTime: false
  }
};

$scope.$watch('myvalue', function() {
  console.log('** date selected **');
}

view:

<umb-editor model="datepickerModel"></umb-editor>

The editor appears with correct config, but the watch does not trigger when I select a date. What am I missing?
