Quick dragger question

So I have a round-based head of a character.

I moved the origin point to the lowest part of the head and have it pivot/rotate from there. I usually use Transform behavior for rotation, but I am just wondering if I could do it with a dragger?

So I put a draggable handle on top of the head, but when I tried to move it, it is somewhat welded and not hinging/rotating like transform behavior does. The attach to already set to hinger, but, still.

So how do I get that smooth rotation like of transform behavior using dragger?

Thanks!
