Javascript Angular / Firebase auto keys has "-" remove or add own

I am working on an angular 2 / firebase project.

I have this function which adds a new record to firebase:

addItem(newTitle: string, newText: string) {
    this.items.push({ title: newTitle, text: newText });
  }

This will add something like this to the firebase database:

So I either need a way to generate my own unique id/key or get firebase to not add the -

How can I do this?
