Javascript does not return results

I made a javaScript script to send data to a php file, the data is sent correctly, then it is processed in php to be used again in javascript, however I can not access the return of this data, javascript does not generate the div that I put or show the alert ().

$(function(){
    carregar(0,12,'Chamadas/testeCarregarAnuncios.php');
    $("#carregarMais").click(function(evento){
        evento.preventDefault();
        var init = $().length;
        carregar(init, 12, 'Chamadas/testeCarregarAnuncios.php');
    });
    function carregar(init, max, url){
        var dados = {init: init, max : max};
        $.post(url, dados, function(data){
          for(i = 0; i < data.dados.length; i++){ 
             $("#cardAnuncios").append('<div class="col s12 m8" id="cardAnuncio">'
