HTML buttons do not work - Javascript - AJAX

I want that when selecting an image of the STATE column of a table I change the image / icon depending on what you choose in the modal created in Bootstrap with two buttons / Button1 or Button2 /. If your initial state collected from the database (by a query query) is state = 1, ask me in the modal if you want to change the state to state = 0 or state2, and so on for each user / row / ID.

It does not do anything when clicking on each button, it opens the modal when clicking on the image.

Code in the table column:

echo "<td onclick=\"cambiar_estado(this);\" width=\"10%\" id=\"".$row['ID_OBLIGATORIO']."\" data-estado=\"".$row['estado']."\">" ?>
<!-- Columna ESTADO del usuario. -->
<center>
<?php
    echo "<a data-toggle=\"modal\" data-target=\"#modalEstado\" style=\"cursor:pointer\">";
        echo "<img src=\"/imagenes/".$row['estado'].".gif\">";
    echo "</a>"; ?>

Modal code:

<div class="modal fade" tabindex="-1" role="dialog" id="modalEstado">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title">Cambio de estados - Ventana emergente.</h4>
                </div>

                <div class="modal-body" style="background-color:#66D6F8;">
                    <p>
                        <center><b>¿Deseas cambiar el estado del usuario/ID?</b></center>
                    </p>
                </div>

                <div class="modal-footer">
                    <span style="float:left">
                                                    <button type="button" id="boton_exit" align="center" class="btn btn-default" data-dismiss="modal">Exit</button>
                                                </span>
                    <button type="button" id="boton_uno" class="boton-estado btn-default">Boton 1</button>&nbsp;&nbsp;&nbsp;
                    <button type="button" id="boton_dos" class="boton-estado btn-default">Boton 2</button>
                </div>
            </div>
            <!-- /.modal-content -->
        </div>
        <!-- /.modal-dialog -->
    </div>
    <!-- /.modal -->

Javascript code:

<script>
    function cambiar_estado(row) {
        var estado = $(row).data('estado');

        var opcion1, opcion2, label1, label2;

        if (estado == 1) {
            opcion1 = 0;
            label1 = "Inactivo";
            opcion2 = 2;
            label2 = "Baneado";
        }else if (estado == 2){
            opcion1 = 0;
            label1 = "Inactivo";
            opcion2 = 1;
            label2 = "Activo";
        }else if (estado == 0) {
            opcion_ = 1;
            label1 = "Activo";
            opcion2 = 2;
            label2 = "Baneado";
        }

        $('#boton_uno').attr('estado', opcion1);
        $('#boton_dos').attr('estado', opcion2);

        $('#boton_uno').html(label1);
        $('#boton_dos').html(label2);

        // $('#modal').modal();
    }

    $('.boton-estado').click(function(){
        var estado = $(this).attr('estado');
        console.log(estado);
    });
</script>
