[Interest] Qml SpinBox Control 2 undo/redo

I'm trying to make an undo redo, I manage to have my whole thing working for user mouse drag n drop, add remove part into my model. One thing that bug me with the control 2 is the spinbox, the value is bind to the mode and the model get changed too, not sure this is the optimal way (I so wish we got 2 way binding like C# one day, this is so deeply needed and not have everybody reimplement there own way).

    id: sequenceIndex_

    value: opsModel.index

        // This is called before value modified

        // The value is already modified, how can I get previous value to make my undo/redo ? seem too late and the value changed as already been called

        target: ops_model
        property: "index"
        value: sequenceIndex_.value

How does one manage to do it with this control?! I guess I will have the same challenge with the ComboBox and all the selector controls (button are fairly easy since I can capture the previous value before doing the action).
