Clojurians Log v2

Hey all, I'm going through the guide here http://pedestal.io/guides/hello-world-query-parameters I actually just copied and pasted their entire code at the end, but I'm still having issues where it doesn't reload changes to the code. What I do:

clj
user=> (require 'hello)
user=> (hello/start-dev)
... some server stuff...

New terminal

curl -i <http://localhost:8890/greet?name=>"Aaron"
; Hello, Aaron

back in hello.clj, change the response to (str "Your name is: " nm ...)

user=> (hello/restart)

curl -i <http://localhost:8890/greet?name=>"Aaron"
; Hello, Aaron

At this point I was expecting it to start saying "Your name is: Aaron". And if I shut down the repl, then start up all over again, it does! But it should do that just from running the (restart) function, no?
