Here is my scenario:   

I have a form, with a checkbox.   

 - When it is checked, I hide another `<div>` that has a termination date input field, which has a `datepicker`.   

 - When the checkbox is not checked, I want to display the the `<div>` with termination date field. User, clicks on the date, and selects one.

The problem I can't figure out: if after selecting the date, the user checks again the checkbox, how to reset the termination date field to nothing?

I placed the code on [jsfiddle](http://jsfiddle.net/z8gEy/15/).

I already tried what seems like a million ways of doing it, and nothing seems to be working.

Any help with this, is greatly appreciated!!!
