As I made these, I changed the tempura and bread crumbs often. If you find that the tempura, or the bread crumbs are not sticking to the onions, or either are too moist and not dry anymore, it's time to dump it out and start again with fresh tempura and bread crumbs. It definitely will make a difference. You will want to add more garlic salt and cajon seasoning to the fresh bread crumbs. The measurements in this recipe are approximate.
