Rails 5.1:为什么在提交表单时我的提交按钮没有被禁用?

<%= bootstrap_form_for(@user, html: { multipart: true }) do |f| %>
  <%= f.text_field :name, required: true, autocomplete: "name" %>
  <%= f.date_select :date_of_birth,
                    required: true,
                    include_blank: true,
                    start_year: Time.current.year - 90,
                    end_year: Time.current.year - 17
  %>

  <%= f.file_field :cv, label: "Your CV", accept:"application/pdf, 
    application/zip,application/vnd.openxmlformats-officedocument.wordprocessingml.document", placeholder: "Choose a PDF or DOC file" %>
  <%= f.hidden_field :cv_cache, id: "cv_cache" %>

  <%= f.submit "Submit application", id: "application_submit_button", data: { disable_with: "Submitting..." } %>
<% end %>

jquery ujs

//= require rails-ujs
//= require activestorage
//= require turbolinks
//= require jquery3
//= require popper
//= require bootstrap

//= require_tree .

data: { disable_with: "Submitting..." }

是否在提交表单时禁用该按钮?我需要采取哪些进一步的步骤来确保按钮禁用?

<%= f.submit "Submit application", id: "application_submit_button", disable_with: "Submitting..." %>

更新2:

disable_with: "Submitting..." data_disable_with data-disable-with

<input type="submit" name="commit" value="Submit application" id="application_submit_button" data_disable_with="Submitting..." class="btn btn-secondary" data-disable-with="Submit application">

data_disable_with="Submitting..." data-disable-with="Submit application"

<input type="submit" name="commit" value="Submit application" id="application_submit_button" data-disable-with="Submitting..." class="btn btn-secondary">

我仍然不知道为什么它不起作用。
