The normal pattern would be:

Add an on change method to the state_id field

on_change="state_id_change(state_id, context)"

Add the on change method to your model.

def state_id_change(self, cr, uid, ids, state_id, context = None):
    values = {'country_id': False}

    if state_id:
        state = self.pool.get('state_model').browse(cr, uid, state_id, context = context)
        values['country_id'] = state.country_id.id

    return {'value': values}

Note that if they clear the state, this will also clear the country but if they select a state, it will look up the related country id and return it. You can put anything you want in the on_change as long as it returns a dictionary.

This assumes OpenERP 7. If you are on 6, leave the context argument out of the XML on_change attribute.

One last thing, you have a typo in your model, _columns is misspelled.
