Definition and Usage
The pagebeforecreate event is triggered when the page is about to be initialized and before jQuery Mobile has started enhancing the page.
Use this event to manipulate content before jQuery Mobile has had a chance to do so. For example, if you want to add data attributes via a script instead of in the HTML source (see example below).
Note: This event is only triggered once per "page" - Every time a page is loaded for the first time, jQuery Mobile caches pages in the DOM (memory), so when you navigate back from pagetwo to pageone (for example), this event will not fire, because then, pageone is already initialized.
