OnClick is not propagating, so that the jQuery function "onClickOutside" (or whatever its name : when you click on page body for exemple), is not called and then jquery plugins using this function won't work in that case, for example :

You have two input text fields, one for date, the other for time.
When clicking on date, a div shows up, and disappears when "click outside". If we click on the time input (using clockpick), the date div won't disappear.
