Qt for Python (PySide/Shiboken)

Hi, Hi can't make Qobject.findChildren work with delegate. qml ListView { width: parent.width height: parent.height model: [1,2,3,4,5] objectName: "blob" delegate: Button { objectName: "bla" height: 100 width: parent.width text:"mokok" + modelData onClicked: ddb.child(root) } }and on the python side, inside de ddb QObject : python @Slot(QObject) def child(self, un): print(un.findChildren(QObject, QRegExp('bla')))it retuns []. Using other objectName works well. I only have this matter with delegate not with other stuff. any idea on it ?
