ListView not updating UI when changing bindable property from ViewModel

Hi there, everyone!

I have a simple listview on my Xamarin application which contains iterates over the menu items from an ObservableCollection:

<views:MenuItemsListView x:Name="_menuItemList"
    ItemsSource="{Binding MenuItems}"
    SelectedItem="{Binding SelectedMenuItem}"
    SeparatorVisibility="None">

    <ListView.Behaviors>
        <behaviors:EventToCommandBehavior EventName="ItemTapped"
            Command="{Binding NavigateCommand}" />
    </ListView.Behaviors>
</views:MenuItemsListView>

• MenuItemsListView is a simple list view with a stackLayout and two labels.

On my ViewModel constructor, I'm inserting the available menus and updating the SelectedMenuItem in order to make the first item initially activated:

public MasterPageViewModel(INavigationService navigationService)
    : base(navigationService)
{
    MenuItems.Add(new MenuItemModel { Icon = "\ue88a", PageName = "HomePage", Title = "Início" });

    MenuItems.Add(new MenuItemModel { Icon = "\ue7fd", PageName = "CustomersListPage", Title = "Clientes" });

    MenuItems.Add(new MenuItemModel { Icon = "\ue871", PageName = "ProductsListPage", Title = "Produtos" });

    MenuItems.Add(new MenuItemModel { Icon = "\ue8cc", PageName = "OrdersListPage", Title = "Pedidos" });

    SelectedMenuItem = MenuItems[0];
    MenuItems[0].IsSelected = true;

    NavigateCommand = new DelegateCommand(HandleNavigate);
}

I can assure the SelectedMenuItem is being correctly updated. Basically, I'm using Prism's SetProperty to update the referenced _selectedMenuItem. For some odd reason, the background color of selected item is never updated (except when navigating, when it works accordingly).

I tried some solutions suggested here and there, but, as of now, none of them worked. I really appreciate if someone can help me with this!
