Widgets stops working after i cache dom and render again.

Widgets stops working after i cache dom and render again.


hi,
in our application we are caching the dom when we change tabs. by
caching i mean we clone whole dom in a javascript variable and keep in
memory. once the user returns to the cached tab we render that dom
again.
what i have created here is a simple example of what we are doing in
our application. here in example i an taking full dom in a variable
when you press "cache and render again". you will see some alerts
which will explain the process.

problem is datepicker or any other widget stops working once i do
this.
waiting for replies,
thanks in advance,
regards,
saurabh
