Autoupdate QTableView

[cyupa]

How can I manage to somehow autoupdate a QTableView that returns data from a MySQL Table trough a QSqlQueryModel.
I add the data into the database from two QlineEdit.

//casuta dreapta jos
    QLabel *added_table_label = new QLabel(tr("Lista websiteuri"));
    QTableView *added_sites = new QTableView;
    QSqlQueryModel *inputlista = db.show_table_sites();
    added_sites->setFixedWidth(500);
    added_sites->setModel(inputlista);
    added_sites->setColumnWidth(0,245);
    added_sites->setColumnWidth(1,245);
    added_sites->show();
    QVBoxLayout *lista_websiteuri = new QVBoxLayout;
    lista_websiteuri->addWidget(added_table_label);
    lista_websiteuri->addWidget(added_sites);

    QLabel *added_table_label = new QLabel(tr("Lista websiteuri"));
    QTableView *added_sites = new QTableView;
    QSqlQueryModel *inputlista = db.show_table_sites();
    added_sites->setFixedWidth(500);
    added_sites->setModel(inputlista);
    added_sites->setColumnWidth(0,245);
    added_sites->setColumnWidth(1,245);
    added_sites->show();
    QVBoxLayout *lista_websiteuri = new QVBoxLayout;
    lista_websiteuri->addWidget(added_table_label);
    lista_websiteuri->addWidget(added_sites);

        const char *argument_email=adresae.c_str();
        db.addtolist(contorsite, argument_site, argument_email);
        website_add->clear();
        email_add->clear();
        contorsite++;
    }
