Validation jquery validate is not deleted when I close the modal bootstrap

Question

How to make jQuery Validate validation messages delete when I close modal Bootstrap?

I have the following codes that are executed when I close the modal by clicking the button Fechar and when I click on the mask. When I open the modal Bootstrap validations are still there.

/**
 * Fechar Modal de Inclusão de Contrato após clique na área fora da modal
 */
$("#mascara").click(function() {
    $(this).hide();
    $(".window").hide();
    $('#myModal').on('hidden.bs.modal', function () {
        limparCampos();
    });
});

/**
 * Fechar Modal de Inclusão de Contrato através do Botão Fechar
 */
$('.fechar').click(function(ev) {
    ev.preventDefault();
    $("#mascara").hide();
    $(".window").hide();
    $('#myModal').on('hidden.bs.modal', function () {
        limparCampos();
    });

});

EDIT1

Friends, the options shown did not work with me. Keep showing the error messages. Follow code snippet:

jQuery(Document). ready(Function() {

var validator = $('#ajax_form_inclusao').validate({
    rules : {
        numeroContrato : {
            required : true...

The code above does the validation. The code below is responsible for closing the modal.

/**
* Fechar Modal de Inclusão de Contrato após clique na área fora da modal
*/
$("#mascara").click(function() {
    validator.resetForm();
    $(this).hide();
    $(".window").hide();
});

/**
 * Fechar Modal de Inclusão de Contrato através do Botão Fechar
 */
$('.fechar').click(function(ev) {
    ev.preventDefault();
    validator.resetForm();
    $("#mascara").hide();
    $(".window").hide();
});

EDIT 2:

I am working with a modal bootstrap, according to the code below. How do I delete the fields and validate jquery in modal?

<!--MODAL DE INCLUIR-->
