Bootstrap Datetimepicker 更改事件未触发

Bootstrap Datetimepicker 更改事件不会无错误地触发。有什么线索吗？

https://github.com/Eonasdan/bootstrap-datetimepicker/blob/master/docs/Events.md https://github.com/Eonasdan/bootstrap-datetimepicker/blob/master/docs/Events.md

$('#datetimepickerStart').datetimepicker();

$('#datetimepickerStart').datetimepicker().on('change', function (ev) {
                alert('!!!');

});

我找到了解决方案

  $('#datetimepickerStart').datetimepicker().on('dp.change', function (event) {
                alert('!!!');
            });
