How to run a specific AJAX call in Rails - ruby-on-rails

Question

I am using has_scope to filer to filter jobs in a show.html.erb page. Once the jobs are filtered or not, the user can click on a job title and have the detail displayed on the same page on a partial. I have two functions in show.js.erb working, except that when the user clicks on the job title, the system run both call again and re-initialize the jobs selection. Can I isolate the second call so it does not run both functions ?
I have the two lines working well.
show.js.erb
$("#job_indiv").html("<%= j render partial: 'jobs/show', :locals => {:job => #job} %>");
(The above function display the individual details of the job)
$('#job_menu_left').html('<%= escape_javascript(render('menu_left')) %>')
(The above function filters the jobs list)
The view:
<div class="job_intro_display">
<%= form_tag job_path, method: 'get', id: "jobs_search" do %>
<div>
<% #industries = Job.all.distinct.pluck(:industry) - ["", nil] %>
Industry:<br>
<% #industries.each do |industry| %>
<div class="btn-filter">
<%= check_box_tag "by_industries[]", industry %> <%= industry %>
</div>
<% end %>
</div>
</div>
<div id="job_menu_left">
<%= render 'menu_left' %>
</div>
<div id="job_indiv">
<%= render 'jobs/show' %>
</div>
<script type="text/javascript">
$(function () {
$('input[type=checkbox]').change(function () {
$.get($('#jobs_search').attr('action'),
$('#jobs_search').serialize(), null, 'script');
return false;
});
$('#jobs_search').submit(function () {
$.get(this.action, $(this).serialize(), null, 'script');
return false;
});
});
</script>
Each ajax should be able to run separately.
