Change handler expressjs

Question

I had this idea to change the handler of a rest request in express on the fly without restarting the server. My idea was something like that

app.use("/test", (req,res) => {
  res.json("hello!");
})
app.use("/test", (req,res) => {
  res.json("bye!");
})

But it doesn't seem to work, because I always get the answer back from the first one. I think express just appends the second one to the same route, but how can I replace them.
