Populate a select with ajax with ng-options using AngularJs - angularjs

Question

With angularJS, I need populate a select with data coming from a ajax call.
I have a controlller called "TabPacProfissionalController".In this controller I do a ajax call to get json data('profissionais object').
So far so good.
My problem is that I get the json data returning from server, but my select is never populate.
What am I missing here?
My ajax return is:
{"results":[{"nr":"8","nome":"AAAAAAAAAAAA"},
{"nr":"17","nome":"BBBBBBB"},
{"nr":"27","nome":"BBBBBAAAAA"},
,{"nr":"1004","nome":"CCCCCCCCC"}]}
HTML
<div class="form-group">
<label for="paciente.texto.sexo" class="col-sm-2 control-label">Profissional:</label>
<div class="col-sm-10" ng-controller="TabPacProfissionalController as tabProfCtrl">
<select class="form-control" ng-model="selectedProf" ng-options="nome for (nr,nome) in tabProfCtrl.profissionais">
<option value=''>Select an option</option>
</select>
</div>
</div>
JS:
app.controller('TabPacProfissionalController', function($http) {
this.profissionais = {};
$http.get('/getStaff?tipoProf=1').then(function(response){
this.profissionais=response.data.results;
console.log(this.profissionais.toString());
},function(error){
console.log(error);
});
});

If you want the label to display the nome property and the value to be the nr property try the following:
<div class="form-group">
<label for="paciente.texto.sexo" class="col-sm-2 control-label">Profissional:</label>
<div class="col-sm-10" ng-controller="TabPacProfissionalController as tabProfCtrl">
<select ng-model="tabProfCtrl.selectedProf" ng-options="profissionais.nr as profissionais.nome for profissionais in tabProfCtrl.profissionais">
<option value="">Select</option>
</select>
</div>
</div>
(key,value) notation you are using is for object data sources, as in if you wanted to iterate through the properties of a single object, rather than a collection of objects which is what you seem to be getting from the $http call.
To see the parsed server response, you could use angular.fromJson(response.data)
Here is a plunker demonstrating the functionality.
