Jquery is returning undefined for one of the generic properties I created

Jquery is returning undefined to one of the generic properties I created, to use with Bootgrid. I am trying to load a modal according to the click event of one of the buttons on the grid, but the modal opens without content. JQuery recognizes the data-action="Details" property, but the data-row-id="'+ row.id +'" property is returned as undefined. If anyone can please me, I appreciate it.

JQuery:

$(document).ready(configurarControles);

function configurarControles() {

        var traducao = {
            infos: "Exibindo {{ctx.start}} a {{ctx.end}} de {{ctx.total}} Projetos",
            loading: "Carregando...",
            noResults: "Nenhum projeto encontrado!",
            refresh: "Atualizar",
            search: "Pesquisa"
        };

        var grid = $("#gridProjetos").bootgrid(
        {
            ajax: true,
            url: "@Url.Action("Listar")",
            labels: traducao,
            searchSettings: {
                characters: 4
            },
            formatters: {
                "acoes": function(column, row) {
                    return '<a href="javascript:void(0)" class="btn btn-info" data-acao="Details" data-row-id="' + row.id + '"><span class="glyphicon glyphicon-list"></span></a> ' +
                        '<a href="javascript:void(0)" class="btn btn-warning" data-acao="Edit" data-row-id="' + row.id + '"><span class="glyphicon glyphicon-edit"></span></a> ' +
                        '<a href="javascript:void(0)" class="btn btn-danger" data-acao="Delete" data-row-id="' + row.id + '"><span class="glyphicon glyphicon-trash"></span></a>';
                }
            }
        });

        grid.on("loaded.rs.jquery.bootgrid", function () {

            grid.find("a.btn").each(function (index, elemento) {

                var botaoDeAcao = $(this);

                var acao = botaoDeAcao.data("acao");
                var idEntidade = botaoDeAcao.data("row-id");

                botaoDeAcao.on("click", function () {

                    alert(acao);
                    alert($(this).data("row-id"));
                    abrirModal(acao, idEntidade);
                });
            });
        });

        //Efetua a pesquisa dinâmica em todos os campos da lista, através do parâmetro "searchPhrase", passado pelo Boosgrid.
