Knob indicator doesn't adjust when its `value` prop is modified though a callback

[Bachibouzouk]

The title should be explicit enough, here are the callback and the visuals

@app.callback(
    Output('knob', 'value'),
    [],
    [],
    [
        Event('radio-choice', 'change')
    ]
)
def knob_reset():
    """reset the knob to 0 when the radio item is toggled"""
    return 0

here's a preview. the knob's value is being set to a certain value with change in boolean switch.
