I like the idea here, but the implementation isn't right. The doc_table is a directive with an isolate scope. You should be changing what you pass into that.

See this line: https://github.com/elastic/kibana/blob/master/src/plugins/kibana/public/discover/controllers/discover.js#L120

OK, I gave it another shot: I removed the code from the doc_table, and injected my variable into the line you pointed me to. Is that better now?

This needs to be rebased on master or have master merged into it.
