JMeter. Receiving scriptSessionId for DWR requests

I've faced a problem that I can't get scriptSessionId using Regular Expression Extractor.

I have an HTTP request that was recorded using Proxy. So I've added a regular expression extractor to the engine.js

But this not helps me to get the scriptSessionID.

Any suggestions what is going wrong? I have a feeling like I've put this post-processor too early or too late. Would be really glad if someone could help me.
