Problems validating radio groups with Javascript

Question

I need to validate a set of radio groups so that at least one is selected by the user.

If I select nothing and click the Next button, the validation seems to work.

The problem is that if I then select an option and click Next, the return of the validation (if (!Fv.isValid()) {......) is returning false and I can’t get out... I put an Alert to test rsrsrs...

I don’t know what I’m doing wrong... Could be some problem with the radios... Does anyone know how to help me?

//JS

(function (global, factory) {
    if (typeof define === "function" && define.amd) {
        define('/pais/paisImport', ['jquery', 'Site'], factory);
    } else if (typeof exports !== "undefined") {
        factory(require('jquery'), require('Site'));
    } else {
        var mod = {
            exports: {}
        };
        factory(global.jQuery, global.Site);
        global.formsWizard = mod.exports;
    }
})(this, function (_jquery, _Site) {
    'use strict';

    var _jquery2 = babelHelpers.interopRequireDefault(_jquery);

    (0, _jquery2.default)(document).ready(function ($$$1) {
        (0, _Site.run)();
    });

    // Example Wizard Form
    // -------------------
    (function () {
        // set up formvalidation
        (0, _jquery2.default)("#formatoArquivoForm").formValidation({
            framework: 'bootstrap',
            fields: {
                rgFormaContato: {
                    validators: {
                        notEmpty: {
                            message: 'Selecione uma opção'
                        }
                    }
                }
            },
            err: {
                clazz: 'text-help'
            },
            row: {
                invalid: 'has-danger'
            }
        });                

        var wizard = (0, _jquery2.default)("#paisImportWizardForm").wizard(options).data('wizard');

        // setup validator
        // http://formvalidation.io/api/#is-valid
        wizard.get("#formatoArquivo").setValidator(function () {
            var fv = (0, _jquery2.default)("#formatoArquivoForm").data('formValidation');
            fv.validate();
            alert(fv.isValid());
            if (!fv.isValid()) {
                return false;
            }

            return true;
        });

    })();

});
