Rails 4 change boolean value in db using button

I am working on simple application to create your music collection. To add album to collection I am using Collection.rb model, it is working very well, but I decided to add a parameter :to_buy to Collection, and add second button "Add to wishlist".

collection_controller:

def create
@album = Album.find(params[:collection][:album_id])
current_user.collect!(@album)
@album.update_attributes(params[:collection][:to_buy])
respond_to do |format|
  format.html { redirect_to @album }
  format.js
end
end

Code for button to add album:

<%= form_for(current_user.collections.build(album_id: @album.id), remote: true) do |f| %>
 <div><%= f.hidden_field :album_id %></div>
 <div><%= f.hidden_field :to_buy, :value => true %></div>
 <%= f.submit "Add to my wishlist", class: "btn btn-large btn-primary" %>
<% end %>

Album is adding to collection, but I want to send value true to :to_buy in collection, and it is still null. Could anyone explain why?

Although GhostRider has valid information, let me explain what we'd do for this:

Custom Method

If you want to update one attribute, I'd make a custom method in your controller & route to it:

#config/routes.rb
resources :controller do 
    post :buy
end

#app/controllers/your_controller.rb
def buy
    @album = Album.find(params[:collection][:album_id])
    @album.update_attributes(to_buy: params[:collection][:to_buy])
    respond_to do |format|
         format.js
    end
end 

#app/views/
<%= form_for(current_user.collections.build(album_id: @album.id), url: buy_path(@album), remote: true) do |f| %>
    <div><%= f.hidden_field :album_id %></div>
    <div><%= f.hidden_field :to_buy, :value => true %></div>
    <%= f.submit "Add to my wishlist", class: "btn btn-large btn-primary" %>
<% end %>

@album.update_attributes(params[:collection][:to_buy])

should be changed to 

@album.update_attributes(:to_buy, params[:collection][:to_buy])

as you need to provide the attribute to be updated. I would also suggest to use where in place of find when querying over the model object.
