I need to take the value of an input and send it to a bootstrap modal. I did a test but I don’t know what I’m missing.

You need to add a Istener to the event "show.bs.modal", adjust your HTML to receive the input value (Note the #text you entered inside . modal-body, it will receive the input value).

The final HMTL code is as follows:

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <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" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <p id="texto">  
        </p>
        <input type="hidden" class="form-control" id="nome-hidden" name="nome-hidden">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
<div class="container centralizar">

  <div class="row">
    <div class="col-md-6 col-md-offset-1">
      <div class="input-group">
        <span class="input-group-addon" id="sizing-addon2">Nome</span>
        <input type="text" name="nome" id="txtNome" class="form-control" aria-describedby="sizing-addon2">
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col-md-2 col-md-offset-1">
      <button class="btn btn-lg btn-info btn-block" class="modalAlerta" data-toggle="modal" data-target="#myModal" id="modalTrigger">Gerar</button>
    </div>
  </div>
</div>

And the JS was as follows:

;(function($) {
  $('#myModal').on('show.bs.modal', function() {
    var nome = $("#txtNome").val();
    $( '#texto' ).text( nome );
  });
}(jQuery));

$('#myModal').on('show.bs.modal', function() {
    var nome = $("#txtNome").val();
    $( '#texto' ).html( nome ); // Vc pode tentar assim..
    $( '#texto' ).append( nome ); // Ou assim vai depender da sua necessidade!
});
