如何在单击复选框时调用对象的方法？

Question

我有回应自由职业者的项目。当项目的所有者选择像表演者这样的自由职业者时，他点击复选框响应。然后单击musst调用方法project.set_performer。我有以下代码，点击复选框后没有任何反应。

Propject.rb

def set_performer(id)
  response = Response.find(id)
    project = response.project
    project.update( performer_id: response.freelancer.id )    
end

项目/ responses.html.erb

<div class="controls">
            <%= check_box_tag 'freelancer_id', @project.set_performer, false, class: 'response', data: { id: "select_freelancer_#{response.freelancer.id}" } %>  
          </div>
