Confirm is flickering

Question

I am trying to add a confirm on 1 event , it is working on firefox but not on chrome , earlier it was working on chrome as well but now not.

Now the confirmation box comes but soon it disappears, it flickers.

Below is the code for this:

$('.job_form').on('submit', function(e) {
    if (!confirm("If this job is posted to more than 1 person, it will go to the first person that accepts it.")) {
      e.preventDefault();
      return false;
    }
});

<%= form_with(model: job, html: {"data-parsley-validate" => '', class: 'job_form'}, local: true) do |f| %>
  //  html fields
  <%= render partial: 'form2', locals: {f: f} %>
<% end %> 

Below is form2

//html fields
<div id="isAllDiv"></div>

<div class="col-md-12 text-center">
 <%= f.submit 'Post Job', class: 'btn btn-primary signin-btn' %>

//html code with other fields

Output of executing $._data( $(".job_form")[0], "events" );

Try by removing the e.preventDefault() or return false from the submit function. You cannot use it together

$('.job_form').on('submit', function(e) {
    if (!confirm("If this job is posted to more than 1 person, it will go to the first person that accepts it.")) {
      e.preventDefault()
    }
});
