Dash Python

In mi code, when i push in dropdown with id which called ‘caracteristicas’, ‘update_sliders’ callback is activated. Why? WHat is wrong?

@app.callback(
    [Output('table','data'),
     Output('table','columns'),
    Output('table','page_count')],
    [Input('caracteristicas','value'),
     Input('table', "page_current"),
     Input('table', "page_size")])
def modify_table(carac,page_current,page_size):
    print("1")
    if carac:

        columns=[{"name": x, "id": x} for x in carac]
        df2 = data.loc[ : , carac]
        df2 = df2.iloc[page_current*page_size:(page_current+ 1)*page_size
        ].to_dict('records')
        lastCaracChoosen = carac.copy()
        return df2,columns,math.ceil(len(data_aux)/page_size)
    
    if carac == []:
        lastCaracChoosen = carac.copy()
    
    columns=[{"name": x, "id": x} for x in todosValores]
    df2 = data.iloc[page_current*page_size:(page_current+ 1)*page_size
    ].to_dict('records')
        
    return df2,columns,math.ceil(len(data_aux)/page_size)

Hum, this should not happen. Are you 100% sure the callback is activated (for example, do you see the print statement of update_sliders every time you update caracteristicas ?)? Could you please upload a standalone script which we could run (including creating dummy data for your data variable) so that we can diagnose what’s going on?

This is my body:

Maybe because of I modify the children that contains the sliders?
