Evolution CMS - Form Lister. does entering numbers with validation work?

Question

MODX

Good day to all!
There was a problem, I wrote a snippet for Thomas, where you can order a call by entering only numbers in the field!
I found the validation class "numeric" for this.
I started testing the form, but it does not send a message to email ...
I.e. works like if I have an empty field, naturally nothing should be sent.
If I enter letters, then the text “Enter the number correctly” pops up, which means it understands that letters are being entered, not numbers, BUT if I enter numbers, then the form simply does not send anything ..
Added ajax + script to the form - but nothing helps
snippet:

<div class="modal_inner modal_request">
    [!FormLister?
    &formid=`request`
    &rules=`{
      "phone": {
        "numeric" : {
          "params": [0,1,2,3,4,5,6,7,8,9],
          "message":"Введите номер правильно"
        }
      }
    }`
    &formTpl=`@CODE:
    <form method="post">
      <input type="hidden" name="formid" value="request">
            <input type="text" name="phone" placeholder="Введите телефон" class="[+phone.errorClass+][+phone.requiredClass+]" value="[+phone.value+]">

    &messagesOuterTpl=`@CODE:<div class="alert alert-danger" role="alert">[+messages+]</div>`

ajax form:

Script:

<script type="text/javascript">
  //see plugin evoAjax
   $(document).on('submit','.modal_request form',function(ev){
        var frm = $('.modal_request form');
        $('.last_button').prop( "disabled", true );
     //alert( frm.serialize());
        $.ajax({
            type: 'post',
            url: '[(site_url)]request', 
            data: frm.serialize(),
            success: function (data) {
   				$('.modal_request').empty();
                $('.modal_request').html( data ); 
            }
        });
        ev.preventDefault();
    });
</script>
