There is an unofficial way.

}

QVariantMap newElement; // QVariantMap will implicitly translates into JS-object
newElement.insert("name","from cpp");
QMetaObject::invokeMethod(
model, // for this object we will call method
"append_", // actually, name of the method to call
Q_ARG(QVariant, QVariant::fromValue(newElement)) // method parameter
);
}
