it's not possible use input's in form with name "elements"

Please, see example:

<form id="form">

<input name="foo" value="foo">

<input name="boo" value="boo">

<input name="elements" value="bug">

</form>

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>

<script>

var $form = $('#form');

console.log($form.serializeArray());

console.log($form.serialize());

</script>

// Output:

Array[1]

0: Object

name: "elements"

value: "bug"

__proto__: Object

length: 1

__proto__: Array[0]

elements=bug
