Azure Mobile Services and Push Notification for Windows Phone 8

I've got some issues with this code (part of scheduled job in Azure Mobile Services):

    var channelTable = tables.getTable('PushChannels');
    channelTable.read({
        success: function(channels) {
            channels.forEach(function(channel) {
                push.mpns.sendToast(channel.PushChannelUri, {
                    text1: "AppName:",
                    text2: "Update!"
                }, {
                    success: function(pushResponse) {
                        console.log("Push sent");
                    },
                    error: function(error) {
                        console.error("Error!");
                    }
                });
            });
        }
    });

My problems are:

• Push notifications are not arriving device
• console.logs are not displaying in "Logs" tab

Could someone help me? Kind regards!
