BOAction not working in Html5.

Hello there.

1) I've created a custom OWL screen and added a button on it.

2) I've created a click event handler for the button that:
     * Executes a BOAction;

     * Refreshes some fields;

It works in silverlight, but seems that the BOAction doesn't execute if I'm using html5 interface.

I concluded that because when I try to debug in html5, the breakpoint does not hit and no trace message is logged.

Anyone knows something about this behavior?

Thanks in advance,

Alexandre.
