django channels not working how does it work i have read docs

iam trying to use channels but not working here is consumer.py

def ws_connect(message, cat_id):
    try:
        cat = Categories.objects.get(pk=cat_id)
    except Categories.DoesNotExist:
        pass
    Group('cat-1').add(message.reply_channel)


def ws_diconnect(message, cat_id):
    try:
        cat = Categories.objects.get(pk=cat_id)

    except Categories.DoesNotExist:
        pass
    Group('cat-1').discard(message.reply_channel)

and this is routing.py :

channel_routing = [
    route('websocket.receive', ws_connect, path=r'^/liveupdate/(?P<cat_id>\d+)/'),
    route("websocket.disconnect", ws_diconnect, path=r'^/liveupdate/(?P<cat_id>\d+)/'),
]

this is signals.py :

@receiver(post_save, sender=Tender)
def send_update(sender, instance, created, raw, using, **kwargs):
    print '>>>>>>>>>>>>>>>>>>>>>>>>>>>>', instance, '2', raw, '3', using, '4', kwargs
    data = json.dumps(
        {'ministry': 'hisham',})
    Group('cat-1').send({'tender': data,})
    print 'Done'

and here is javascript :

<script type="application/javascript">
    var ws_scheme = window.location.protocol == "https:" ? "wss" : "ws";
    alert(ws_scheme +"://" + window.location.host + "/liveupdate/1/");
    var socket = new WebSocket(ws_scheme +"://" + window.location.host + "/liveupdate/1/");
    socket.onmessage = function(e) {
    alert(e.data);
};
    socket.onopen = function() {
        console.log("Connected to  socket");
    };
    socket.onclose = function() { console.log("Disconnected to  socket"); }

</script>

when iam tring to save tender signal fire but nothing in browser i.e no alert of data what is the wrong with my code any ideas

Instead of websocket.receive use websocket.connect. Receive is used when client is sending data to server.

route('websocket.connect', ws_connect, path=r'^/liveupdate/(?P<cat_id>\d+)/'),

When are you sending data instead of tender use text as a Key.

Group('cat-1').send({'text': data,})
