Click on the button running as many times as you have

I have the following situation:

<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#segunda_tab" ><?php echo $array_dia_da_semana_s[0] ?></a></li>
<li><a data-toggle="tab" href="#terca_tab"  ><?php echo $array_dia_da_semana_s[1] ?></a></li>
</ul>

<div class="tab-content">
<div id="segunda_tab" class="tab-pane tab tab-label fade in active">
    <?php
        $id_linha_tabs = 1;
        echo("<font size='5' style='font-weight:bold;'>" . $array_dia[0] . "</font>");                      
        $data_string = $array_dia[0];
        $dia_da_semana = 0;
        $id_da_tabela = 0;                      
        include('consulta_01_dds.php');                                             
    ?>  
</div>

<div id="terca_tab" class="tab-pane fade">
  <?php
        echo("<font size='5' style='font-weight:bold;'>" . $array_dia[1] . "</font>");                      
        $data_string = $array_dia[1];
        $dia_da_semana = 1;
        $id_da_tabela = 1;                      
        include('consulta_01_dds.php');     
  ?>
</div>
</div>

In the file query_01_dds.php I have the following code:

<br>
<table>
    <td>
        <tr>
            <?php echo($dia_da_semana)?>
        <button class="button1" id="<?php echo($dia_da_semana)?>"><?php echo($dia_da_semana)?>
        </tr>
    </td>
</table>    
<br>


<script>    
     $(function()
    {   
        $('.button1').click(function()
        {
            bb = $(this);
            $(".tab-content div").each(function( index ) 
            {
                if($(this).attr('class').indexOf('active') != -1)
                {   
                    alert(" B Indice3: " + index+ ' value..: '+ $(bb).val()+ ' - id '+ $(bb).attr('id'));

                }
            });
        });
    });

</script>

At first everything works as it should. The tabs appear, each tab content in its respective place, however when I press the button of class button1 the click returns the alert with the information I asked for correctly, the problem is that it returns me as many times as the tabs I place. In this case the alert appears 2 times. Home Example .. If I add another LI with href="#quarta_feira" and its respective div id="quarta_feira" then the click will cause the alert to appear 3 times ..
Is the logic wrong? Is not that how you use nav-tabs and tab-pane?
Thanks in advance for your attention.
