use HTML::FormFu;

my $form = HTML::FormFu->new;

$form->populate({
    elements => [
        {
            type => 'ComboBox',
            name => 'foo',
            options => [
                [ 1, 'one' ],
                [ 2, 'two' ],
            ],
        },
    ],
});

$form->process;

$form->get_element({ type => 'ComboBox' })->options([
    [ 3, 'three' ],
    [ 4, 'four' ],
]);

$form->process;

print $form;

The above example works as expected - with the select menu containing
'3' and '4' options.

The only thing I can think of, is that you're calling options()
directly on $combobox->elements->[0]
rather than on the combobox - don't do this - you should consider the
combobox a blackbox with regards its child elements.

If that's not it, I'll need to see some code.

That is equivalent to:
    values: 'USA UK Canada'

I think you mean:
    values: ['USA', 'UK', 'Canada']
