Hi Everyone, I need a little help with shortcode
i have a single page made with elementor pro, and there's a elementor form
I need to put Facebook event code ( initiatecheckout ) that starts only when user start to write in name field

I've already a little code and it works well with an html form, i just want to make it work fine with elementor form

here the little code to get initiatecheckout:

<script>
var primavolta = 0;
$(document).ready(function(){
$("input[name=fullname]").change(function(){
if(primavolta == 0){
fbq('track', 'InitiateCheckout');
primavolta = 1;
}
});
});
</script>


and here the html form code:

<form id="contact" action="thank-you.php" method="post">
<fieldset>
<input name="fullname" placeholder="Nome e Cognome" type="text" tabindex="1" required>
</fieldset>
<fieldset>
<input name="phone" placeholder="Cellulare (per conferma)" type="tel" tabindex="2" required>
</fieldset>
<fieldset>
<input name="address" placeholder="Via, Città, Provincia" type="text" tabindex="3" required>
<div style="font-size:14px;font-weight:normal;">Es. Via Aldo Moro 66, 06100 Perugia.</div>
</fieldset>
<fieldset>
<button name="submit" type="submit" id="contact-submit" data-submit="...Sending">INVIA ORDINE</button>
</fieldset>
</form>
