QWebElement and ComboBox

[BOBOS]

So im using QWebElement to fill up a online form and im having some trouble with the country combobox.
My code is somehitng like this:

QWebElement document = frame->documentElement();
QWebElement country_element = document.findFirst("select[id=countryCombobox]");
QWebElementCollection country_option = country_element.findAll("option");
for(QWebElementCollection::iterator it = country_option.begin(); it != country_option.end(); it++) {
    if((*it).attribute("value") == "DE") {
        (*it).setAttribute("selected", "true");
    }
}

So for instance if i want to select Germany it dosent do what i really want. It selects Germany in the list but it dosent put it as the selected value.(instead of --)
