Binding a control to another control added to a Canvas at run-time
===

I'm new to WPF and I need a little help. How do I bind the Text of a TextBlock on my Window to the Text of another TextBlock that will be added to a Canvas at run-time;

i.e
Assuming this
 

    <TextBlock Name="tb" Text="{Binding ???}"/> <Canvas Name="cv"
    ></Canvas>


CODE BEHIND

    TextBlock tb1 = new TextBlock();
    tb1.Text = "Test"; 
    cv.Children.Add(tb1);

Again I'm new to WPF

I want to be able to display the Text in tb1 in tb
