我选择的字段无法正确填充无脂肪框架

I am confronting a problem trying to fill my select field with the fat-free framework.

I try to use axios as in most tutorial, I point to "response.data" but nothing fills in my field.

I have this code in my model:

public function ReadUserData($action) {
    if (strcmp($action, "read") == 0) {
        global $f3;
        $user = $this->db->exec("SELECT * FROM users");
        return json_encode($user);
    }
}

I have this in my controller:

$Users = new UserModel($this->db);
$DataUser = $Users->ListDatabaseUser();
if (isset($_GET['action'])) {
  $data = $Users->ReadUserData($_GET['action']);
  $f3->set("users", $data);
}

and in vue js I have:

<script type="text/javascript">
  var Myapp = new Vue({
  el: "#app",
  delimiters: ['{%', '%}'],
  data: {
    heading: 'test',
    dataSelect: null,
    makes_options: []
  },
  created() {
    axios.get('http://localhost/?action=read')
    .then(function(response) {
          Myapp.make_options = response.data;
          console.log(Myapp.make_options);
      });
  }
});

I also try to replace:

Myapp.make_options = "{{ @users }}" but without sucess :/

For display that I have this in html:

<label for="Select">Select</label>
<select class="form-control" name="dataSelect" id="dataSelect" v-model="dataSelect">
  <option v-for="option in makes_options" :value="option.id">{% option.username %}</option>
</select>

Currently my field is empty and I do not understand why my json is not interpreted correctly
