Build a CMS With Laravel video 5.3 javascript issues

@Jeremy McPeak, I did really enjoy your course but on video 5.3 am having some issues with the javascript as I keep getting (DefaultDate is not recognized!) using chrome inspector. having removed the DefaultDate: ‘{{$model->published_at}}’ in my script the date and time display on focus on my textbox but i can’t pick any date and time I want. I was wondering if anyone can advise how I can fix it.

Thanks for your help

Joshua.
