how to change the look direction of a character at end of path

[ninadpradhan]

I tried 

m_OnEndReached.AddListener(Listener);

private void Listener(CurvySplineMoveEventArgs arg0)
{
    //transform.Rotate(transform.rotation.x,180, transform.rotation.z);
    transform.rotation = Quaternion.Euler(transform.rotation.x,180, transform.rotation.z);
}

in SplineController..

I get the callback but the object never rotates?
