POST hook does not appear to work on test repository

I created a test repository in order to test POST hooks

https://bitbucket.org/eradman/hook-test

Then added a hook with the following URL:

http://eradman.com:9003/

Next I started a simple test server:

::::ruby
require "json"
require "sinatra"

set :port, 9003
set :bind, '0.0.0.0'

post '/' do
    reply = {:status=>"ok"}
    puts params
    reply.to_json
end

When I push commits to this test repo nothing seems to happen. Are hooks broken
or did I miss something?
