ontorrent callback isn't fired in browser

[LaurentVB]

Hello,
I tried the snippet from the README with webtorrent 0.11.2 in chrome and firefox 34.0 and chrome 38 on windows 7.
The callback is never fired.
Webtorrent on the command-line with the same magnet link downloads the file right away.
So I tried the following code (inspired by the cmd.js file):

var WebTorrent = require('webtorrent')
var client = new WebTorrent()
var torrent = client.add(magnet_uri);
torrent.on('infoHash', function () {
    console.log('infoHash');

    torrent.on('metadata', function () {
        console.log('metadata');
    })
})

And the console shows the 'infoHash' log, but the 'metadata' log never shows up.
Anyidea what could be the issue here?

Regards

Laurent

WebTorrent can only download torrents that are explicitly seeded to the WebTorrent network. Torrent clients need to support WebRTC to peer with web browsers. Currently, no clients support it but you can use http://instant.io/ to seed torrents that WebTorrent can download.

Thanks for this clarification.
