wp_mail, sending image attachment with mutilple fields uploading a single image - wordpress

Question

i know it's a duplicate question, but please be kind with me, i have to solve this. I have a custom form in Wordpress, sending an email template via AJAX. Everything is working fine, except those single fields attachments in the image below. those input fields are triggered by jquery to receive the image and i have tested if the form input file are not empty with Jquery before sending the email. When i put the hard code it's works, otherwise it's not. Please guide me to solve this. Any help would be appreciate.
my HTML form:
<form id="tratamento_form" method="POST" action="#" enctype="multipart/form-data">

<label for="name" class="">Nome completo</label>
<input id="name" class="form-control " placeholder="José Aparecido " type="text" name="nome" id="name" autocomplete="off">
