[support] refreshing jcarousel item list without page reload

[Aldo Martinez Selleras]

This only happened when the select change the first time, by default, are
not rendering this element!!!

Could be because the itemLoadCallback is called twice, by default and when
the select change?

By the way, the method isn't .clear(), the name is .reset() ;)

I see other thing here!, the scroll is not working!!! When I click the
NextBtn is called the URL /classification/ $(select).val().

Why this ?
