Kotlin: Enable/Disable Bluetooth With Switch Material button

Question

I want to manage the bluetooth but my layout didn't change anything when I click on the switch On/Off

Here is my layout:

<data>
        <variable
            name="viewmodel"
            type="[...]viewmodels.BluetoothViewModel" />
        <import type="android.view.View" />
    </data><com.google.android.material.switchmaterial.SwitchMaterial
            android:id="@+id/toggle_bluetooth"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="@dimen/text_size_medium"
            android:checked="@{viewmodel.state.bluetoothActivated}"
            android:text="@{viewmodel.state.bluetoothActivated?@string/toggle_bluetooth_activated :@string/toggle_bluetooth_not_activated}"

In my BluetoothViewModel :

class BluetoothViewModel : BaseViewModel<BluetoothState>(BluetoothState()){
fun changeBluetoothState(bluetoothState: Boolean) = updateState {
        it.copy(
            bluetoothActivated = bluetoothState,
            bluetoothDevices = emptyList()
        )
    }```

my bluetoothstate : data class BluetoothState ( var bluetoothActivated: Boolean = false,

then my fragment:

 binding.toggleBluetooth.setOnCheckedChangeListener { _, state ->
           bluetoothViewModel.changeBluetoothState(state)
       }
