avoiding code duplication for Properties in PySide2

Question

I am tired of writing the same code for declaring Properties for PySide2:

class BackEnd(QObject):

    my_prop_updated = Signal()

    @Property(bool)
    def my_prop(self):
        print('getter invoked'))
        return self._my_prop

    @my_prop.setter
    def set_my_prop(self, value):
        print('setter invoked')
        self._my_prop = value
        self.my_prop_updated.emit()

    def __init__(self):
        super().__init__()
        self._my_prop = None

Is there any way to make use of python descriptors with Properties? Something like so:

class QTPropBool(Property):
    my_prop_updated = Signal()

    def my_getter(self, obj):
        print('getter invoked')
        return self._my_prop

    def my_setter(self, obj, value):
        print('setter invoked')
        self._my_prop = value
        self.my_prop_updated.emit()

    def __init__(self):
        super().__init__(bool, self.my_getter, self.my_setter, notify=self.my_prop_updated)


class BackEnd(QObject):
    my_prop = QTPropBool()

It gives me an error:

AttributeError: 'PySide2.QtCore.Signal' object has no attribute 'emit'

Probably because it's Property class, not QObject and I am not invoking QObject's constructor. Is there any way to avoid code duplication?
