jquery mobile

I have a new project where I have a multi-page site. I'm trying to go from page 1 to page 2 and calling javascript to access a php page so I can print data from mysql. It's working well ONLY AFTER A MANUAL REFRESH. The data will show up for a split second, then disappear. I've put the javascript function call in the body of my 2nd page.

I've tried pagebeforeshow and other events, but it's still the same problem.

Any help would be appreciated.
