❔ xamarin listview doesnt update

hi so i have a weird problem in my code behind i have 2 methods

        private void SearchList(object sender, TextChangedEventArgs e)
        {
            listView.ItemsSource = SearchService.GetSearches(e.NewTextValue);
        }

        private void Refresh(object sender, EventArgs e)
        {
            listView.ItemsSource = SearchService.GetSearches();
            listView.EndRefresh();
        }

        private void SearchList(object sender, TextChangedEventArgs e)
        {
            listView.ItemsSource = SearchService.GetSearches(e.NewTextValue);
        }

        private void Refresh(object sender, EventArgs e)
        {
            listView.ItemsSource = SearchService.GetSearches();
            listView.EndRefresh();
        }

one is called when searching and one is called when refreshing all i do in both is just reassign the ItemSource to new Items the weird part is that when i refresh nothing updates on screen while when i search and remove the text from search bar it is updated after so basically looks like listView.ItemsSource = SearchService.GetSearches(e.NewTextValue); this line works while this does not listView.ItemsSource = SearchService.GetSearches();

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
