Call default WPF Textbox Paste handler from my command binding

I have declared a WPF Textbox with a command binding for Paste:

<TextBox x:Name="txtMsg">
    <TextBox.CommandBindings>
        <CommandBinding Command="ApplicationCommands.Paste" Executed="TxtMsg_OnPaste"/>
    </TextBox.CommandBindings>
</TextBox>

My code-behind is

private void TxtMsg_OnPaste(object sender, ExecutedRoutedEventArgs e)
{
    if (Clipboard.ContainsText())
    {
        // Let the textbox paste text its normal way
        // This code is called, but the textbox doesn't paste anything!
        e.Handled = false;
    }
    else
    {
        // My logic for other clipboard formats
        // ...
        e.Handled = true;
    }
}

The problem is setting e.Handled = false does not cause the textbox to paste anything. Nothing is pasted when the clipboard contains text!

How do I get the WPF Textbox to handle the Paste command normally in this case?

Call the Paste() method on the TextBox. Or you can just get the text and set it yourself -- same difference.
