Bindable property not being updated

I have a custom control that extends from content view:

<ContentView Opacity=".8" BackgroundColor="#fafafa" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="TamarianApp.EmptyLabel">
    <StackLayout>
        <BoxView HorizontalOptions="FillAndExpand" HeightRequest="3" BackgroundColor="#f1f1f1" VerticalOptions="Start"/>
        <StackLayout HorizontalOptions="CenterAndExpand" VerticalOptions="CenterAndExpand">
            <Label HorizontalOptions="Center" VerticalOptions="Center" TextColor="Gray" Text="{Binding Text}"/>
        </StackLayout>
    </StackLayout>
</ContentView>

Backend:

public partial class EmptyLabel : ContentView
    {
        public static BindableProperty TextProperty = BindableProperty.Create(
            "Text",
            typeof(string),
            typeof(EmptyLabel),
            defaultBindingMode: BindingMode.TwoWay,
            defaultValue: "",
            propertyChanged: TextPropertyChanged
        );


        public string Text
        {
            get
            {
                return (string)GetValue(TextProperty);
            }
            set
            {
                SetValue(TextProperty, value);
            }
        }

        public EmptyLabel()
        {
            InitializeComponent();

            BindingContext = this;
        }

        private static void TextPropertyChanged(BindableObject bindable, object oldVal, object newVal)
        {
            ((EmptyLabel)bindable).Text = newVal.ToString();
        }
    }

I want to control the visiblity of the EmptyLabel control from the view model by binding a property to it :

    ``<local:EmptyLabel IsVisible="{Binding HasNoImages}" Text="No Images"></local:EmptyLabel>``

For instance If I changed IsVisible="{Binding HasNoImages}" toIsVisible="false" it works.

Everything else on the page binds to there controls ( theres a lot more code ), but when binding to the custom control from the binding context, it ignores it. What is happening here?
