How to record CDJ2000nxs + DJM900nxs using Live9?

Hi all, how can I record while I'm playing my set using Ableton Live 9?  

I got 2 CDJ2000nxs connected to a DJM900nxs, all plugged in to my Macbook, using USB and LAN via Rekordbox.

I'm using channel 2 and 3 on the mixer btw.

I've put as attachment, my actually configuration of DJM utility and Live9. Right now I'm not getting any sound "In" ableton.

I know there are a lot of topics about this argoment but can't find a right one that helps me out with my settings.

Thanks :)
