How to set at runtime in my dependency property

DefaultUpdateSourceTrigger = UpdateSourceTrigger.LostFocus

Here is my example:

public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(TagEditLookupBox),
            new Telerik.Windows.FrameworkPropertyMetadata(string.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, new PropertyChangedCallback(OnTextSearchChanged)));

        private static void OnTextSearchChanged(DependencyObject o, DependencyPropertyChangedEventArgs args)
        {
            var view = (o as NasaEditBox);
            if (view == null)
                return;
            //...
        }

        [DefaultValue("")]
        public string Text
        {
            get
            {
                var value = GetValue(TextProperty);
                if (value == null)
                    return string.Empty;
                else
                    return value.ToString();
            }
            set
            {
                SetValue(TextProperty, value);
            }
        }

I set  property

BindsTwoWayByDefault = true,

but how to do that with DeafultUpdateSourceTriger


I do not want to set in xaml, runtime in my dependency property only.
