Denis,Thank you for your help. It is working.
At the end I did not create the vector of enrichment inside the loop, just
a smart pointer like this
std::shared_ptr<Enrichment<dim>> enrich_ptr(new Enrichment<dim> (k,n,q));
then pushed back to my functions vector:
functions.push_back([=] (const typename Triangulation<dim>::cell_iterator
&) -> const Function<dim> * {return enrich_ptr.get();});
