Node.JS does not save the data of a form

Good afternoon everyone! I'm trying to save the data from a form, and I have no idea why it's not saving. I remember that I would have to use a stringify, or something like that, but I can not see it. Below are the view (ejs) and the index.js information! (I've hidden the host information and privacy connection.):

<div class="row">
<form class="col s12" action="/salvar" method="post">
    <div class="row">
        <div class="input-field col s12">
            <label for="cognition_name">Nome</label>
            <input id="cognition_name" type="text" class="validate">
        </div>
        <div class="input-field col s12">
            <label for="cognition_age">Data de Nascimento</label>
            <input id="cognition_age" type="text" class="validate">
        </div>
        <div class="input-field col s12">
            <a class="waves-effect waves-light btn" 
id="send_cognition_people">SEND</a>
        </div>
    </div>
</form>
</div>
