Custom TransportHandler not called

Hi All,

The custom TransportHandler is not called when I am publishing a page. How to fix it ?Please find the source code.I'm using AEM 6.1.

I read one thread where it is mentioned that service ranking needs to be set higher.But the link provided does not have enough details.
