[jQuery] [validate] Pb with button

[cage31]

Hi,

I use the validate plugin for my site but, in my form,  there are some
buttons with metadata. Something like this:
<button id="btnCancel" class="bnbutton {bnAction:131328}"
type="button">

1. the plugin control the button element. Why ? Theses are not input.
2. the plugin search the validate function bnAction and hang because
it not exists. What can I do ?

I'll have the same probleme with select tag.

Thanks

Gerard
