Hi, I have this js code

var pusher = new Pusher('my pusher key', {
        cluster: 'ap2'
    });
    var channel = pusher.subscribe('my-channel');

    channel.bind('my-event', function(data)
    {
        console.log(data);
    });

This is my Laravel code

protected $pos_invoice;
public function __construct($pos_invoice)
{
    $this->pos_invoice = $pos_invoice;
}
public function broadcastOn()
{
    return new Channel('my-channel');
}

public function broadcastAs()
{
    return 'my-event';
}

This is the calling code

return event( new \App\Events\New_pos_online_order_event('aa'));

Now is the code

channel.bind('my-event', function(data)
    {
        console.log(data);
    });

always returns [] on the console, so I tried this

public function broadcastAs()
{
    return 'my-event.'.$this->pos_invoice;
}

and this

public function broadcastOn()
{
    return new Channel('my-channel'.'asdfasdf');
}

When I change anything

public function broadcastOn()
{
    return 'my-channel';
}

public function broadcastAs()
{
    return 'my-event';
}

The code does not work and returns nothing on the console So how can I pass parameters on Pusher and Laravel using js Thanks..
