I have a simple form with an order by param. When my dropdown is changed, I call this:

```
$.post("/busca", $("#order_form").serialize(), dataType: "script")

```

On the rails controller side I have a simple `format.js` to handle the ajax calls.
Thing is that this isn't working. The `js.erb` template is never rendered.

My log shows `Processing by BuscaController#index as */*` and I have no idea what the `*/*` stands for. Can someone help me?
