Multiple executions of script loaded in data-role="page" with pageshow event

Multiple executions of script loaded in data-role="page" with pageshow event

I have script that is loaded in the  data-role="page" area of my page.

 It contains an event that runs on pageshow ('#id').live('pageshow',etc) when i load the page the first time is fine, if I load it the second time from a link in the same parent page it executes twice.


Any ideas
