JavaScript Rails code not working in application.js -

- 

  $(document).ready(function() {      $('#client-select2').select2();    });

if place code above application.js, not respond if place in _form.html.erb file, does. know why is?

views/orders/_form.html.erb

<script type="text/javascript">   $(document).ready(function() {      $('#client-select2').select2();    });  </script>  <%= simple_form_for(@order) |f| %>   <%= f.error_notification %>     <%= f.input :code %>     <%= f.association :client, collection: client.all, label_method: :name, value_method: :id, prompt: "choose client", required: true, input_html: { id: 'client-select2' } %>     <%= f.submit %> <% end %>

application.html.erb has

<%= javascript_include_tag 'application' %>

the reason select2 and/or jquery included after application.js,

if instance, if order is:

//=require_self //=require select2 //=require jquery

the jquery/select2 functions not available in application.js since application.js included before.

could share header of application.js?
