JQuery / Javascript Drag and Drop Calendar Events -- 2

I have a calendar that I created that needs the ability to drag and drop events. The events are already populated and the drag and drop feature is partially completed. I am to the point where I can drag and drop an event to a different day on the calendar but if I try to drag that event back to the same day it started with, it does not work. I just need some assistance fixing this bug. If you cannot complete this within 3 hours, please do not bid on this project. Include the term 'Event Specialist' in your bid description. Thanks!
