return to the main page doesn't fire pagebeforecreate or pagecreate ONLY the first time

return to the main page doesn't fire pagebeforecreate or pagecreate ONLY the first time

Hi everybody!
I'm using jquery mobile since version 1.0 (today i'm using 1.2.0 RC2) , and i've a recurring problem.
I'm using it with knockout and i need to reload the content of the linked page. To do this, i call my ko.applybindings when the pagebeforecreate is called.
I also changed these variables when mobileinit is called:

$.mobile.page.prototype.options.domCache = false;
$.mobile.ajaxEnabled = true;
$.mobile.changePage.defaults.reloadPage = true;

It works when I reload any page and go to any other page, but when i come back to the first page, pagebeforecreate is not fired. If i go to another page it works, and if i come back to the first page again, this time it works.

If you know how to fix this or how i can reload any page (even the first) without losing the beautiful screen transitions, i'm listening :)

thanks you
