How to use notify on property of the List type?

I need to get a notify signal on change of the collection property. But it seems that setter didn’t work with lists?

    @GObject.Property
    def collection(self) -> list:  # pylint: disable=method-hidden
        return self._collection

    @collection.setter
    def collection(self, collection: list) -> None:
        self._collection = collection

Are you setting the property?:

obj.collection = ['foo', 'bar']

or just mutating the list?

obj.collection.append('baz')

The former emits a notify signal as expected here.

appending didn’t trigger the notify signal. So just need to reset was here:

self.collection.append({"name": lexicon_name, "tags": []})
self.collection = self.collection

My previous error was that I’m setting it with
self.collection = self.collection.append() where’s append returns None. But yesterday, after 6 hours straight of debugging I thought that it was a great idea.
My bad.
