You are not triggering the PropertyChanged-event with the correct property name "TextProperty" - or am I missing something? I've never used Prism. Try:

public string TextProperty
{

    get
    {
        return selectedText;
    }
    set
    {
        SetProperty(ref selectedText, value, "TextProperty");
    }
}

or better yet:

private void MyCommandExecuted(object obj)
{
    SetProperty(TextProperty, string.Empty);
    MessageBox.Show("Command Executed");
}

and remove the SetProperty call from the property setter.
