If you haven't used those rubber grommets before, you may find them easier to install if you put the grommet in FIRST, then slide the cord through it. The grommet MUST be a snug fit in the hole, or it's worse than useless.
Just as a second thought
if you had the appropriately sized hole you could use an NM 3/8 clamp, just like they use for outlet boxes, etc. Would guarantee the wire doesn't slide through and put a strain on a connection/wire nuts etc.
BTW, the toothed trowel is there to guarantee that the carpet gets some adhesive to hold onto (forms high spots).....I've seen jobs where the installer used tons of adhesive and still never managed to get the carpet/tile to stick...good work!
