Elastic Email + JavaScript

form.html

<form id="subscribeForm">
  <input id="email-input" type="text" />
  <button type="submit">Submit</button>
</form>

newsletter.js

function SetupNewsletterSubscribe(publicAccountId, listName, formId, onSuccess) {
    var eeUrl = "https://api.elasticemail.com/v2/contact/add";
    var email = jQuery("#email-input");

    var form = jQuery("#" + formId).submit(function (event) {
        event.preventDefault();
        jQuery.post(eeUrl, {
            email: email.val(),
            publicAccountId: publicAccountId,
            listName: listName
        }, function () { }, "json").done(function (result) {
            if (result.success == true) {
                onSuccess();
            }
        }).fail(function () {
            // Do something here if it fails...
        });
    });
};

// DOM Ready, call the function defined above with parameters
jQuery(function () {
    SetupNewsletterSubscribe("**MY_PUBLIC_ACCOUNT_ID**", "NameOfEmailList", "subscribeForm", function () {
        // Do stuff here when the email address has been added to the service!
    });
});

Correct, this doesn't send emails and it's not meant to.

This simply adds the given email address to your list of contacts in Elastic Email, under the specified list (from listName)

oh that's the reason, anyway it works fine, just the last question, how to clear field after submission?
now i'm using
document.getElementById("subscribeForm").reset();

$('#email-input').val('');
