How to add custom Button in Notification with onclick listener?

Question

I have an app in which I have to add a custom layout with imageview, textview and button. To do this I have used RemoteView. Everything is working fine but I want to add on click listener on button. I searched a lot but not found any solution for that issue. How do I do that?

private void customNotification(String title, int message, byte[] image) {
    // Using RemoteViews to bind custom layouts into Notification
    RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.custom_notification_card);
    builder = new NotificationCompat.Builder(this);

    builder.setSmallIcon(R.mipmap.ic_launcher_round);
    builder.setAutoCancel(false);
    builder.setOngoing(true);
    builder.setContent(remoteViews);
    builder.setCustomBigContentView(remoteViews);
    builder.setPriority(android.app.Notification.PRIORITY_MAX);

    Intent i = new Intent(context, CNotificationHomeActivity.class);
    i.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(this, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(intent);

    // Locate and set the Image into customnotificationtext.xml ImageViews
    ByteArrayInputStream imageStream = new ByteArrayInputStream(image);
    Bitmap theImage = BitmapFactory.decodeStream(imageStream);
    remoteViews.setImageViewBitmap(R.id.imagenotileft, theImage);

    // Locate and set the Text into customnotificationtext.xml TextViews
    remoteViews.setTextViewText(R.id.title, title);
    if (message == 1) {
        remoteViews.setTextViewText(R.id.count_text, RewardUtil.fromHtml("<font color='#8AC34B'><b>" + message + "</b></font>" + " notification"));
    } else {
        remoteViews.setTextViewText(R.id.count_text, RewardUtil.fromHtml("<font color='#8AC34B'><b>" + message + "</b></font>" + " notifications"));
    }
    // Create Notification Manager
    notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // Build Notification with Notification Manager
    notificationManager.notify(NOTIFICATION_ID, builder.build());

}

code of custom_notification_card.xml
