If you're writing a cascade of callbacks then just use promises. There's no reason to be needing to cascade callbacks pretty much all libraries now support promises and the rest can be promisified. I'm not calling it a Panacea but Promises are idiomatic Node Javascript now and there's almost no reason for mutliple levels of nested callbacks anymore.
