I was trying to update a members property by using a web control, i don't get any error, but the member doesn't see to update...

This is the code i am using:

[code]

        if (umbraco.cms.businesslogic.member.Member.IsLoggedOn())
        {
            Member m = umbraco.cms.businesslogic.member.Member.GetCurrentMember();
            m.Password = wachtwoord.Text;
            m.getProperty("cor_naam").Value = naam.Text;
            m.getProperty("cor_telefoon").Value = telefoon.Text;
            m.getProperty("cor_dienstverband").Value = dienstverband.Text;
            m.getProperty("cor_landnummer").Value = landnummer.Text;
            m.LoginName = gebruikersnaam.Text;
            m.Save();

        }

[/code]

Do i maybe forget something?
