I would do something like this:
db.define_table('nominee',Field('name'),Field('region_id',db.Regions))
def get_nominees():
region_id = request.vars.region_id
return TAG[''](*[OPTION(r.name,_value=r.id) for r in
db(db.nominee.region_id=region_id).select()])
def get_form():
script="""
jQuery(function(){jQuery('input[name=region_id]').keyup(function()
{
var region_id = jQuery('input[name=region_id]').val();
jQuery.post('{{=URL('get_nominees')}}', { region_id:
region_id }, function(data, textStatus, jqXHR){
Query('select[name=nominee]').html(data);
});});});
"""
form =
FORM(INPUT(_name='region_id'),SELECT(_name='nominee'),INPUT(_type='submit'),script)
