Jquery function scope after load()

Jquery function scope after load()

Hi newbee to jquery here so forgive me if this is simple....
 
I have a php doc reports.php inside of which i have a div element which gets loaded via jquery .load(listreports.php);

Inside the parent document (reports.php) is some jquery functions that i want to access from within the loaded div (listreports.php).

What/how is the best way to do this i have read things on livequery and event delegation. Is there any way to refresh the whole document after the load so that the jquery from both docs would be accesable from both docs... hope that all makes sence?!
