Update slider based on data

Dash Python
1

Why don’t sliders update when I select different data from a dropdown menu?
Normal dash items do and I don’t see anything wrong here…

    dcc.Store(id = 'memory-output-slider'),
    
    html.Div([
            daq.Slider(
            id = 'timelineSlider',
            #min = 0, 
            #max = 100, 
            value = 30,
            #marks = {'25': 'mark', '50': '50'}, 
            disabled = True,
            size = 1920,
            color = {'default': '#C51426'}
        )
    ], style = {'margin-top': '20px', 'margin-bottom': '20px'}),


@app.callback(Output('memory-output-slider', 'marks'),
              [Input('my-dropdown', 'value')])
def timeline_slider(deal_ids_selected):
    return timeline_process.timeline_slider(deal_ids_selected, timelineList)

@app.callback(
    Output('timelineSlider', 'marks'),
    [Input('memory-output-slider', 'marks')])
def route_slider(marks):
    return timeline_process.route_slider(marks)
