JQM caching has nothing to do with the HTML document cache. JQM "caching" refers to pages that are kept in the DOM. The HTML document cache is maintained by your browser.

JQM always caches the initial page that was loaded. I've sometimes played some games with making that first page a blank page and then immediately changing to the second page. Only makes sense for, say, a hybrid app (like Cordova/Phonegap) where there is only a single initial entry point through the main page.

HTML document caching depends on the headers sent by your server, and any proxies that are passed-through.

I don't know what you mean by "manifest version number". There is more you are not telling us. Is this a "web app" of some sort?

My first fiddle! :)

BTW, you have some invalid HTML. It's clearly shown in red in the Fiddle. You should  use use &, not & to display an ampersand.

datesandtimes.html will not be loaded from your server! The origin of a Cordova/Phonegap site is the local filesystem in the device, not your server. If you mean to load it from your server, you need to prepend your website. e.g. example.com/datesandtimes.html.

You can't use simple pagebeforeshow to solve this. The page will probably show before the response is ever received.

You will need to use a pagecontainer widget beforeload callback. The page change will be deferred until you resolve the deferred provided in the beforeload callback. When your Ajax callback has been called, and you have inserted the content into the page, then you can resolve  deferred, and processing of the page will continue.
