jqrelcopy datepicker problem

Good Day,

include(JQRelcopy.php) [<a href=‘function.include’>function.include</a>]: failed to open stream: No such file or directory

I got this problem when i try to put this code in my widget

'jsAfterNewId' => JQRelcopy::afterNewIdDatePicker($datePickerConfig),

but my jqrelcopy works for my datepicker.

the problem is when i click on the duplicated datepicker, the original one is being edited.

Thanks in advance!!

like error says you do not have included file, check is file included, and make import or maybe include file with Yii::import();
