EventLogger ignores source name defined in constructor

I'm using EventLogger for logging in my app, but all my logs have source set to "Node.js" instead of string which I defined in EventLogger constructor.

For example:
var EventLogger = require('node-windows').EventLogger;
var log = new EventLogger('TestLogger');
log.info('Test');

creates log in Windows Logs / Application with source "Node.js" instead of "TestLogger"

My Node.js version: 0.10.27,
OS: Windows 8.1 x64
