Mixing radio buttons and text box

I am trying to combine switches and text field for one value:

= f.radio_button :system, "bacteria"
Bacteria
= f.radio_button :system, "mammalian"
Mammalian
= f.radio_button :system, "yeast"
Yeast
= f.radio_button :system, "insect"
Insect
= f.radio_button :system, "other"
Other:
= f.text_field :system, class:"input-small"

When I send a message, nothing happens, because an empty value is set in the parameters, even if the radio is checked (I think it is considering a text field).

I tried to give a different name to the text box and replaced the system value in the controller after the update, but it looks dirty way ...

Do you have any cleaner ideas?

:

= f.radio_button :system, "bacteria"

= f.radio_button :system, "mammalian"
Mammalian
= f.radio_button :system, "yeast"
Yeast
= f.radio_button :system, "insect"

= f.radio_button :system, nil, id: 'other_system_radio', 
                checked: radio_checked?('system', f.object.system) 
Other:
%input.input-small#other_system_text{ value: text_input?('system', f.object.system) }

( , ):

def radio_checked?(type,val)
  case type
    when 'system'
      ['bacteria', 'mammalian', 'yeast', 'insect'].include?(val) ? '' : 'checked'               
    end
  end

def text_input?(type,val)
  case type
    when 'system'
      ['bacteria', 'mammalian', 'yeast', 'insect'].include?(val) ? '' : val
  end       
end

Javascript "", :

@handle_other_field = ->
  $('#other_system_text').focus( -> $('#other_system_radio').attr('checked','checked'))
  $('#other_system_text').keyup( -> $('#other_system_radio').val($(this).val()))
