Partial specialization bug or me?

Hello, I would like to know why the code in main chooses the primary
template and not the specialization:

//Class
template <class T>
class MyVecIter {
public:
     T * elem_;

     MyVecIter(T * elem) : elem_(elem) {}

     void next() { ++elem_; }
     T & get() { return *elem_; }

     void equals(const MyVecIter & other) { return this->elem_ ==
other.elem_; }
};

template <class Iter>
struct iterator_traits_new {
   ...
};

template <class T>
struct iterator_traits_new<MyVecIter<T>> {
....
};

template <class FwdIter, class FwdIter2>
void copy_new(FwdIter && itbeg, FwdIter && itend, FwdIter2 &&
itbegcopy)
{
     typedef std::iterator_traits_new<FwdIter> tr;
     typedef std::iterator_traits_new<FwdIter2> tr2;
     ...
}

int main(int argc, char * argv[])
{
     int arr[10] = {3, 4, 5, 1, 2, 7};
     std::vector<int> arr2(10);
     copy_new(&arr[0], &arr[0] + 6, arr2.begin());
     MyVecIter<int> veciter(arr2.data()), veciter2(arr2.data() +
arr2.size());

     //This alogrithm specializes iterator_traits_new<FwdIter> with the
general template
     //instead of the specialization
     std::copy_new(veciter, veciter2, &arr[0]);
}

If someone can help. I'm confused why this doesn't work. I think that
MyVecIter<int> should
choose the partial specialization for iterator_traits_new.
Any help? Thanks for your time.
