It's much easier to get help if you put sample code in a jsFiddle, where we can run and edit it.
I can't look at your page source from my mobile, but my first question is: are
you wrapping your elements in document.id('element_name') or using pure DOM
methods? Without document.id() or $(), elements won't get the Mooishness in
IE8, where natives aren't extensible.
