Datatable 1.10 erase data when filtering

I am inserting data in a table with datatable, at the time of using the filter it filters, but it deletes the data that was already loaded in the table.

<div class="jarviswidget jarviswidget-color-blueDark" id="wid-id-2" data-widget-editbutton="false">

                <header>
                  <span class="widget-icon"> <i class="fa fa-table"></i> </span>


                </header>

                <!-- widget div-->
                <div>

                  <!-- widget edit box -->
                  <div class="jarviswidget-editbox">
                    <!-- This area used as dropdown edit box -->

                  </div>
                  <!-- end widget edit box -->

                  <!-- widget content -->
                  <div class="widget-body no-padding">

                    <table id="tabla" class="table table-striped table-bordered table-hove tabla_ot" width="100%">
                      <thead>
                        <tr>
                          <th>Dato1</th>
                          <th>Dato2</th>
                          <th>Dato3</th>
                          <th>Dato4</th>
                          <th>Dato5</th>
                          <th>Dato6</th>
                          <th>Dato7</th>
                          <th>Dato8</th>
                          <th>Dato9</th>
                          <th>Dato10</th>
                          <th>Dato11</th>
                          <th>Dato11</th>
                        </tr>
                      </thead>
                      <tbody>
                       <!-- los datos se cargan aca , pero al usar el filtro de datatable se borran-->
                      </tbody>
                    </table>

                  </div>
                  <!-- end widget content -->

                </div>
                <!-- end widget div -->

              </div>
<!-- agrego el filtro y el paginado-->
$( document ).ready(function() {
   $('#tabla').DataTable( {
    scrollY: 300,
    paging: true
} );


 <!-- inserto los datos al tbody con jquery-->
 $.each(obj.lista, function (ind, elem) { 

    $('#tabla > tbody').html('<tr id="token()" class="row_ot" onclick="Redirec('+elem.valor1+')"><td>'+elem.valor2+'</td><td>'+elem.valor3+'</td><td>'+elem.valor4+'</td><td>'+elem.valor5+'</td><td>'+elem.valor6+'</td><td>'+elem.valor7+'</td><td>'+elem.valor8+'</td><td>'+elem.valor9+'</td><td>'+elem.valor10+'</td><td>'+elem.valor11+'</td><td>'+elem.valor12+'</td><td>'+elem.valor13+'</td></tr>');     
    });

The data is loaded at the beginning of the search even if it finds a match, it deletes the data of tbody , it occurs to me that maybe there is a datable function that cancels this behavior
