How to raise a mouse event on a dynamically added user control?

This is the code for dynamically generating user controls:

//Message is the class with properties and List<> listofMessages
foreach (Message item in Message.listofMessages)
{
UserCKocka novUc = new UserCKocka();
novUc.Margin = new Thickness(5);
novUc.Width = 180;
novUc.Height = 180;

//Increase tag number
stTaga++;
//Tag user control with the number stTaga
novUc.Tag = stTaga;


//Adding the datas and image for the newly created user control
Uri slikaPot = new Uri(item.Slika, UriKind.RelativeOrAbsolute);
BitmapImage slika = new BitmapImage(slikaPot);
novUc.slikaKocka.Source = slika;

//Textblock pošiljatelj
novUc.txtPosiljateljKocka.Text = item.Od;
novUc.txtZadevaKocka.Text = item.Zadeva;
novUc.SporociloKocka.Text = item.Vsebina;


wrap.Children.Add(novUc);
}
