George is just not getting the click for quiet thing at all

I bought a new clicker, which is louder than the one I found in a draw, I cut up some cheese and some chicken and some puppy treats, I got him to realise what the clicker meant by clicking and treating without him having to do anything at all. Then I sat in front of the crate with the door open and clicked and treated if he stayed inside nicely, which he did, I shut the door then opened it straight away, quite a few times, he just looked at me. Then I shut the door and I moved a bit away from the crate, clicking for quiet every couple of seconds, so far so good, then I left the room, literally for a millisecond and he practically threw himself at the door and screamed like a maniac, so I waited for quiet and clicked and treated, over and over again for 20 minutes, he throws a wobbly every time I leave the room even for a second to start with, then he’ll go to bed and carry on whining and moaning for what seems like an eternity, then he’ll stop, and I go in to treat him and he’s laying down in his bed, I can’t not treat him then, but as soon as I do he comes out of his bed and starts again, even if I’m still there arrrrrghhhhhhh
This probably reads like no sense at all, please tell me what I’m doing wrong if I am?or would it be better just to let him get in with it and ignore him till he stops screaming ?
