How to dynamically initialize a select2 in angularjs

Hello everyone, I'm using the select2 plugin in my project. I need to create multiple selects2 dynamically, by angular. I have a vector of objects (with id, name) and I need from an event, in a function to generate a select to of each object, being able to differentiate the key by id. Can anyone help me?

Function:

angular.forEach(camada.filtros, function (filtro)
        {
            var s = "select_multiple"+filtro.id;
            $('#myModalBody').on('DOMNodeInserted', s, function () {
                $(this).select2();
            });

HTML:

<div class="modal-body" id="myModalBody" ng-repeat="filtro in filtros"> 
                        <select class="select_multiple" id="select_multiple{{filtro.id}}" multiple="multiple" style="width: 400px;" ng-model="filtrosCamadasSelecionadas" >
                            <option>asdasd</option>
                            <option>vvvvv</option>
                            <option>bbbbbb</option>
                            <option>aaaaaaa</option>
                            <option>xxxxxx</option>
                        </select>
                    </div>

The code above is not working, it's only a part to get an idea. I tried to use this idea with some links I saw, but I did not get anything yet.
