[jQuery] [plugin] How to change message while the page is blocked using blockUI plugin

<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:arial,helvetica,sans-serif;font-size:12pt">Hello people, i'd like to know if it's possible change de message
while the page is block by "blockUI" jquery plugin. I've tried a lot
of things, but none was good. One thing i've tried was using CSS
selectors like:
$('blockUI blockMsg blockPage').innerHTML
but it hasn't worked.
Any idea?
