The problem still remains in IE.
I'm using JQuery 1.6.4 and the latest version of JQuery Mobile ( http://code.jquery.com/mobile/latest/jquery.mobile.min.js ).
@titoliviolustosa - We are looking into to this. Can you confirm if it is still a problem and which versions of IE you tested? Thanks!
If this is still an issue on IE...
See #4413 - value for filter property should be opacity=10 ?
Do we have to add -ms-filter property for IE8? (http://www.quirksmode.org/css/opacity.html)

I looked at the 3 issues @titoliviolustosa refered to and tested the submit button in all possible ways on IE7 (using IETester), IE8 and IE8 in quirksmode. No matter where I clicked on the button, the submit event was triggered.
Closing as fixed.
