WPF simple bind in code behind

Question

I try to learn WPF, I have problem with basic binding, at the beginning I want to set bind in code behind. May anyone know what I make wrong?

Fils CS

public partial class BindInCodeBehind : Window, INotifyPropertyChanged
{
    private string _myText;

    public string MyText
    {
        get { return _myText; }
        set
        {
            _myText = value;
            OnPropertyChanged("MyText");
        }
    }

    public BindInCodeBehind()
    {
        InitializeComponent();

        var bind = new Binding();
        bind.Source = MyText;
        bind.Path = new PropertyPath("Content");

        MyLabel.SetBinding(Label.ContentProperty, bind);

        MyText = "New tekst";
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

File XAML

<Window x:Class="WpfBindingLearn.BindInCodeBehind"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="BindInCodeBehind" Height="300" Width="300">
    <Grid>
        <Label Name="MyLabel" Content="Wait for binding"></Label>
    </Grid>
</Window>

Path is set in relation to current binding source. Your source (which is a String) does not have Content property. You can set Source to Window and Path to MyText

var bind = new Binding();
bind.Source = this;
bind.Path = new PropertyPath("MyText");
