Remote event handler not fired

I have a remote event handler hosted in azure, that is not firing or not sure whether it is terminated after fire. 

Basically i want to not allow some words in project name while creation. So i created a remote event handler that check name in projectcreating evnet, and cancel the event if it contains a word "..." . It works fine when i add event handler to my onpremise service, but nothing happens in project online site. But the service hosted in azure is same. 

Do I need to do anything specially for project online? 

The help I need for,

1. is there anyway to see whether the event handler is getting fired from project online? and the status ?

Thanks in advance

Thanks, Saravanan PRS
