I think it should be like this:

typedef CGAL::Triangulation_vertex_base_with_info_2<Index, Gt> Info;  // I 
replaced K with Gt
typedef CGAL::Triangulation_face_base_2<Gt> Fb;                       // I 
added this one so that vertex and face type use the same kernel
typedef CGAL::Triangulation_data_structure_2<Info,Fb> Tds;
