Having trouble with a custom UserControl and it's properties

[taevt-iscte]

Hello there, I've defined a UserControl as follows:

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:AvaloniaTestApp.Controls"
             x:Class="AvaloniaTestApp.Controls.CopyableToClipboardTextBoxUserControl"
			 x:DataType="local:CopyableToClipboardTextBoxUserControl">

    <Grid>
        <StackPanel Orientation="Horizontal" Margin="0,-1,0,-1">
            <Label Content="{Binding Caption}" />
            <Label Content=":" Margin="-8,0,0,0" />
            <Button>
                <Image Source="avares://AvaloniaTestApp/Assets/copy-icon-25.png" Width="10" Height="10"/>
            </Button>
            <TextBlock x:Name="TheTextBlock" Text="{Binding Text}" />
        </StackPanel>
    </Grid>
</UserControl>

And it's code-behind:

using Avalonia;
using Avalonia.Controls;
using Avalonia.Markup.Xaml;

namespace AvaloniaTestApp.Controls;

public partial class CopyableToClipboardTextBoxUserControl : UserControl
{
    // Define Styled Properties for Caption and Text
    public static readonly StyledProperty<string> CaptionProperty =
        AvaloniaProperty.Register<CopyableToClipboardTextBoxUserControl, string>(nameof(Caption), defaultValue: "Caption");

    public string Caption
    {
        get => GetValue(CaptionProperty);
        set => SetValue(CaptionProperty, value);
    }

    public static readonly StyledProperty<string> TextProperty =
        AvaloniaProperty.Register<CopyableToClipboardTextBoxUserControl, string>(nameof(Text), defaultValue: "Text");

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

    public CopyableToClipboardTextBoxUserControl()
    {
        // Ensure DataContext is set if needed.
        InitializeComponent();
    }

    private void InitializeComponent()
    {
        AvaloniaXamlLoader.Load(this);
    }
}

However when I use it as such:
<local:CopyableToClipboardTextBoxUserControl Caption="Id" Text="Id" />
There is no text displayed, can someone help me get it working please?
