How to force page reload/refresh of previous page when back button is pressed?

This question was asked in the jQuery Mobile forum and the last entry offered an apparently easy solution but I could not make it work. In that forum ( link) I posted my setup attempt and aked help from the author but I am not certain if s/he is still monitoring it.

I have also attached a text document of my forum entry.

Any help will be appreciated!!
