e.preventdefault does not work in submit

I have a simple form with two inputs and a button to send it. I am trying to make the submit not work by default to be able to do things with the data before sending it to the server but, I do not know why, I can not avoid the submit.

I guess in the end it will be silly but I can not find it ...

Here the form

<form id="formID">
    <input type="email" id="loginName" placeholder="Usuario" required autofocus>
    <input type="password" id="loginPass" placeholder="Contraseña" required>

    <button type="submit">Enviar</button>
</form>

I've also tried with action="/" but it's still the same.

Here the jquery

$('#formID').on('submit', function (event) {
            event.preventDefault();
});

I've also tried it with $("#formID").submit(function(event){}); and return false but it's still the same, when you hit the button or "enter" the page is reloaded.

I do not know what else happens to me to try ... Any ideas?

I tried with the code you provide in the post and it works correctly, maybe it's the browser cache, try cleaning by pressing Crtl + F5

Look here I leave your code, it works correctly ...

PS: If you see a lot of code, it's because it's the bootstrap base template 4
