modal call does not work (bootstrap)

Question

Good morning! I’ll rephrase the question: mount a table that receives data and a link to edit this data. So far so good.

The click on this link should open the modal for data editing. I already checked the references to Bootstrap and Jquery and I can’t understand why I still show the error message: Uncaught Typeerror: $(...). modal is not a Function

Below the snippets of my code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Edit

<div class="modal" id="modalUsuario">
            <div class="modal-dialog">
                <div class="modal-content">
                    <!-- Cabeçalho do Modal -->

You don’t need to call a function to open the modal. Just put in the tag <a> the attributes:

data-toggle="modal" data-target="#modalSenha"

In the data-target you put the modal id. Only this opens the modal:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<a href="#" data-toggle="modal" data-target="#modalSenha">Alterar senha</a>
<!-- Modal -->
<div class="modal fade" id="modalSenha" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Título do modal</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Fechar">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Fechar</button>
        <button type="button" class="btn btn-primary">Salvar mudanças</button>
      </div>
    </div>
  </div>
</div>

    <a href="#" id="alterarSenha">Alterar senha</a>

    <script>
        $("#alterarSenha").click(function() {
            $("#modalSenha").modal("show"); 
        })
    </script>
