Adding to a collection if I've bound it dynamically

[stuartlangridge]

I'm using this.$binding to bind my collection manually, which is great. However, if I do that, then how do I add documents to my firestore? I can't just use this.$firestore.(collectionname).add because that was never created, so I don't have a reference to the collection that I can use to add to it...?

(Ah, I don't use this.$firestore for that; I can just use the globally created firestore object as firestore.collection("whatever").add({...}), exactly the same as I do when binding. I'll close this.)
