To be quite honest I'm stuck trying to override Backbone's sync() method for a Model, I have the signature for the function in place, and it gets triggered correctly, but **I don't know what to put in the function body** in order for it to make a default call to DELETE but **with extra arguments**.
ie.

```
class Master.Models.Member extends Backbone.Model
  urlRoot: '/api/members/'

  sync: (method, model, options) ->
    params = _.clone options
    Backbone.sync method, model, params

```

I call it like this:

```
......
remove: ->
  @model.destroy
    collective_id: the_id

```

My intention there, is to pass the **collective\_id** param you see there to the server. But even though it's inside the options hash for sync() and I clone it, *It won't make it to the server!*
**How can I send that extra param to the server?**

(As it is, the only thing that reaches the server is the Model's id)

Thanks in advance!
