Error finding zip with jquery via zip

I am developing an edit page where the user data is displayed on the screen. In it, we have a new address button, clicking it opens a modal with the address fields (zip, street, neighborhood etc ), but this modal is formed in jquery by clicking on the new address button:

$('#add-row-address').click(function (e) {
        e.preventDefault();
        var codigo = $(this).data("codigo");
        var title = "Cadastro de endereço";
        var body = '<form autocomplete="on" class="form-address" id="form-address" action="ctb-address"> <div class="row-f">\
                            <div class="row-f">\
                                <label>\
                                    Rua\
                                </label>\
                                <input id="logradouro" class="inpt-null" name="rua_end" type="text"/>\
                            </div>\
                            <div class="row-f">\

        ModalForm(title, body);
    });

I do not know if this is why the search does not work, I put the zip and not search, I put the street and also not search, but in the form of registration that is in another page works perfectly, I am using a code of the via CEP adapted by a forum member:

var inputsCEP = $('#logradouro, #bairro, #localidade, #uf, #ibge');
    var inputsRUA = $('#cep, #bairro, #ibge');
    var validacep = /^[0-9]{8}$/;

    function limpa_formulario_cep(alerta) {
        if (alerta !== undefined) {
            alert(alerta);
        }

        inputsCEP.val('');
    }

    function get(url) {
        $.get(url, function (data) {
            if (!("erro" in data)) {
                if (Object.prototype.toString.call(data) === '[object Array]') {
                    var data = data[0];
                }
                $.each(data, function (nome, info) {
                    $('#' + nome).val(nome === 'cep' ? info.replace(/\D/g, '') : info).attr('info', nome === 'cep' ? info.replace(/\D/g, '') : info);
                });
            } else {
                limpa_formulario_cep("CEP não encontrado.");
            }
        });
    }

    $('#logradouro, #localidade, #uf').on('blur', function (e) {

        if ($('#logradouro').val() !== '' && $('#logradouro').val() !== $('#logradouro').attr('info') && $('#localidade').val() !== '' && $('#localidade').val() !== $('#localidade').attr('info') && $('#uf').val() !== '' && $('#uf').val() !== $('#uf').attr('info')) {

            inputsRUA.val('...');
            get('https://viacep.com.br/ws/' + $('#uf').val() + '/' + $('#localidade').val() + '/' + $('#logradouro').val() + '/json/');
        }
    });

    $('#cep').on('blur', function (e) {
        var cep = $('#cep').val().replace(/\D/g, '');
        if (cep !== "" && validacep.test(cep)) {
            inputsCEP.val('...');
            get('https://viacep.com.br/ws/' + cep + '/json/');

        } else {
            limpa_formulario_cep(cep === "" ? undefined : "Formato de CEP inválido.");
        }
    });

Someone there? Help !!
