node.js socket.io emit not working

I've got the following config:

app.set('port', process.env.PORT || 3000); var httpserver = http.createServer(app).listen(app.get('port'), function(){ console.log('Express server listening on port ' + app.get('port')); }); var io = require('socket.io')(httpserver); app.all('/blockcallback', function(req, res){ res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "X-Requested-With"); getTxSender(req.query.tx,function(ref_wallet){ (..) }); io.emit('status', {'message': 'done'}); res.send('*ok*'); }); 

index.html

<script src="http://localhost:3000/socket.io/socket.io.js"></script> <script> var socket = io.connect('http://localhost:3000'); socket.on('status', function(datos){ alert('received'); }); </script> 

ok when i call http://localhost:3000/blockcallback looks like everything works perfectly, but i am not getting the 'status' call on the clientside.

my js console shows:

Error in event handler for extension.onRequest: undefined Stack trace: undefined localhost/:1 Error in event handler for extension.onRequest: undefined Stack trace: undefined extensions::uncaught_exception_handler:9 Stack trace: undefined extensions::uncaught_exception_handler:9 

I don't understand what's happening...
