rails won't send_data as file

Question

I'm having problems with Rails method: send_data

Here's my action:

def export
  send_data(current_user.contacts.to_csv,
    type: 'text/csv; charset=utf-8; header=present',
    disposition: 'attachment; filename=contacts.csv'
  )
end

This will not promt for a download, it just render the result on the screen. I've tried both pow and thin servers.

I can't figure out what I'm doing wrong?

I'm using rails 4.0.0.beta

EDIT:

CURL headers:
