* blur.datetimepicker 

Invalid

My code:

<div class="input-group date" id="datetimepicker" data-target-input="nearest">
	<input type="text" class="form-control datetimepicker-input" id="date"
		   data-toggle="datetimepicker" data-target="#datetimepicker"/>
</div>

<script type="text/javascript">
	$(function () {
	   $('#datetimepicker').datetimepicker({
			locale: 'zh-cn',
			format: "YYYY-MM-DD",
			icons: {
				time: 'fa fa-clock',
			},
		});
		$("#date").on("blur.datetimepicker",function () {
				alert(666)
			}
		)
	});
</script>
