Select2 options appear when selecting a

I am using Select2 to load data remotely and it is bringing the results normally, however when selecting one of the options returned all exist and I could not identify why, it follows the code:

Javascript

$('.js-data-example-ajax').select2({
    ajax: {
        url: "/Home/PopularUsuarios",
        dataType: 'json',
        type: "post",
        delay: 250,
        theme: 'clasic',
        data: function (params) {
            return {
                objPesquisa: params.term, // search term                              
            };
        },

        processResults: function (data, params) {
            params.page = params.page || 1;
            data.forEach(function (d, i) { d.id = i; })

            return {
                results: data,
                pagination: {
                    more: (params.page * 30) < data.total_count
                }
            };
        },
        cache: true
    },
    escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
    minimumInputLength: 1,
    templateResult: function (data) {
        if (data.loading) return data.text;
        var markup = '<option value="' + data.Matricula + '">' + data.Nome + '</option>'
        return markup;
    },
    templateSelection: function (data) {
        return data.full_name || data.text;
    }
});
