angularjs - Angular Strap: Date Range (Start Date Not Working) -

i building simple angular search form, uses bootstrap design framework , angular strap module (found here: http://mgcrea.github.io/angular-strap/).

everything works great except dynamic date ranges based on angular models.

what want quite simple: second date input starts 1st input selected. heres code not work:

depart date (1st input) [works fine]

<input required name="dapart_date" class="form-control" id="leave_date" placeholder="mm/dd/yyyy" ng-model="flightsearchdata.depart_date" data-date-format="mm/dd/yyyy" data-use-native="true" data-autoclose="true" data-min-date="today" bs-datepicker> 

return date (2nd input) [data-start-date doesn't work]

<input required name="return_date" class="form-control" id="return_date" placeholder="mm/dd/yyyy" ng-model="flightsearchdata.return_date" data-date-format="mm/dd/yyyy" data-use-native="true" data-autoclose="true" data-min-date="{{flightsearchdata.depart_date}}" data-start-date="{{flightsearchdata.depart_date}}"  bs-datepicker> 

data-min-date works fine data-start-date works if hard code date.

any suggestions...?

it not solution, quick workaround makes datepicker usable such case.

i added datefrom watch , update dateto accordingly:

$scope.$watch('datefrom', function() {          if ($scope.datefrom) {              $scope.dateto = new date($scope.datefrom.gettime());               // basic date manipulation                                                            $scope.dateto.setdate($scope.datefrom.getdate() + 1);          }      });

it makes dateto datepicker change view focus on selected date. it's not perfect, works me.
