At first thanks for your support,

I looked at the transaction log of the contract and the transaction was successful,
Have you tried reloading the page? On the main network it can take a while, some
of my transactions took more than 20 minutes, others only 1-2.

I experienced an issue with web3.js sometimes not reacting to events, but after a reload
everything was fine again.

Edit: Sorry this bug was my fault! I fixed another one and updated the client with the
address of my test network, It should work in a few minutes!
