Don't destroy page after closing

I am loading some data and then i am using it in virtual list when specific page is opened.
User can click item from that list and then i use ‘back’ class on virtual list item so the page is close when he chose something.
When the page is closed it is destroyed and all listeners and that virtual list is gone. How to prevent this?
I would want it to load that data by xhr only one time and then this page stays in document node.
Any ideas?

I am using framework 7 -v 3.4.2
