Answer 1

An HTML form reset button for a form rests the form to the initial state. In this case back to the values it had when the form loaded. A HTML form reset button does not CLEAR the form or CLEAR the session.

Answer 2

wondering why you are using session for where typicalls form params should be used? In order to clear HTML session you would need to trigger a call back to the originating controller just like you would to post but when it receives via this call. It does a session.invalidate() and then renders same view again. You should try to stick with params for forms. The fact that you have the session information already really no need to post it via a form. Your controller receiving the form would be aware of that same session value.
You could easily create a jquery functionality that you do with a button that triggers and a resetform. jQuery/Javascript function to clear all the fields of a form
Or if that does not work you could try for example in your case:
<g:form ..>
..
<button onClick="clearName();" name="clickme">
</g:form>
<g:javascript>
function clearName() {
$('#name').val();
}
</g:javascript>
