SuiteScript 2.0 saveRecord - Dialog Module

Hi guys! I hope you all are doing fine!

I'm trying to deploy a script that will validade if a field value is true or false (checkbox). Case the field value = false, than I would like to raise a dialog with "Ok" and "cancel" button, and when the user press "Ok" it will save it anyway. In case of press "cancel" it will return to the form.

But when the field = false and the user press "Ok" the record isn't saved. BTW: When the field = true, it works fine.

This is my code:

/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 * @NModuleScope SameAccount
 */
define(["N/currentRecord", "N/runtime", "N/ui/dialog"], /**
 * @param {currentRecord} currentRecord
 * @param {runtime} runtime
 * @param {dialog} dialog
 */ function (currentRecord, runtime, dialog) {
  /**
   * Function to be executed after page is initialized.
   *
   * @param {Object} scriptContext
   * @param {Record} scriptContext.currentRecord - Current form record
   * @param {string} scriptContext.mode - The mode in which the record is being accessed (create, copy, or edit)
   *
   * @since 2015.2
   */
  function pageInit(scriptContext) {
