Hook not working

Am i just stupid or is something wrong...

I'm running this but the messages are never being send...

``` js
module.exports = function (robot) {

robot.on("plus-one", function (plusone) {
var blacklist = ['vim', 'dickbutt', 'something'];

if (blacklist.indexOf( plusone.name) !== -1) {
return robot.reply("Sorry Peon you cant tamper with " + plusone.name);
}
return robot.reply("hey im running last command from" + plusone.from);

});
```

This is with slack adapter if that makes any difference.
