angularjs bootstrap ui 0.13 datetimepicker doesn't pop up -

i'm trying use https://github.com/zhaber/datetimepicker in angular application somehow datepicker doesn't pop when input clicked. here's example: http://plnkr.co/edit/ftwlpjiwxbc8eehxjit0?p=preview , controller's content (rest can find in plunkr):

$scope.initdate = function(){   $scope.date = new date(); }  $scope.initdate(); 

note: if use 'ui-bootstrap-tpls-0.12.1.js' popup work, need 0.13.0

angular ui 0.13 requires angularjs 1.3.x or above, , make sure use latest version of widget: https://github.com/zhaber/angular-js-bootstrap-datetimepicker
