Using traco but the column is not translating in the database

Question

My rails app was using translatable_column to load the config/locales/he-IL.yml content to its own column in a table's column.

the rails app is built with 3.0.19 and ruby 1.8.7, I installed traco gem "traco", "~> 1.0.0" I am not sure which traco version is compatible with 1.8.7. but I know its good with activerecord>3.

  create_table "statements", :force => true do |t|
    t.text     "name_en_us"
    t.integer  "study_phase_id"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "position",                      :default => 1, :null => false
    t.text     "name_zh_cn"
    t.text     "name_de_de"
    t.text     "name_ja_jp"
    t.text     "name_es_es",     :limit => 255
    t.text     "name_it_it",     :limit => 255
    t.text     "name_ar_iq",     :limit => 255
    t.text     "name_et_ee",     :limit => 255
    t.text     "name_da_dk",     :limit => 255
    t.text     "name_en_ca"
    t.text     "name_en_au"
    t.text     "name_en_gb"
    t.string   "name_nl_nl"
    t.text     "name_en_sg"
    t.text     "name_sk_sk",     :limit => 255
    t.text     "name_cs_cz",     :limit => 255
    t.text     "name_ru_ru",     :limit => 255
    t.string   "name_ko_kr"
    t.string   "name_pl_pl"
    t.text     "name_fr_fr"
    t.string   "name_he_il"
  end

There are a lot of statements in the he-IL.yml file in config/locales

in my statement.rb model I have

translates :name
