Update composable when list changes

I've got a composable on a Screen which shows a list of Track items (favourites):

var favourites: MutableList<Track> by mutableStateOf(mutableListOf())

@ExperimentalFoundationApi@Composableprivate fun ResultList(model: FreezerModel) {    with(model) {        if (favourites.isEmpty()) NoDataMessage("No favourites yet")        else {            LazyColumn(state = rememberLazyListState()) {                items(favourites) {                    TrackCard(it, model)                }            }        }    }}

On click events, I am updating my favourites list (add/remove item). How can I make my composable reflect these changes immediately (like to re-draw itself or something similar)? So far, it only works when I first switch to another screen.
