JQuery :: When Using .post(), Page Is Reloaded And Serialized Data Being Added To The URL?

I'm trying to make an ajax post to some php and whenever the user clicks the submit button, it reloads the page and is adding the serialized data to the URL thus breaking the page and giving me an error that I do not have a person selected. I've tried adding "return false;" everywhere I can and it still doesn't work. Here's my code:

// EDIT CONTACT AJAX

$("editForm").submit(function() {

$.post("/ajax/edit-contact.php", $("editForm").serialize(),
function(data) {[code]...

// I've tried adding a "return false;" here and it doesn't work
}
// I've tried adding a "return false;" here and it doesn't work

);
// I've tried adding a "return false;" here and it doesn't work
