Problem when displaying image inside modal

Question

I need to display a list of selected images in a modal, but it is displayed only after clicking (focusing) somewhere in the modal.

Excerpts from the code:

HTML:

<label>Imagens: </label>
<fieldset class="">
    <div class="divImg" ng-repeat="item in modelCheckList.listImagens" id="ID_{{item.nome}}" ng-click="">
        <img width="40px" height="30px" src="{{item.imagem}}">
        <button ng-click="removeImg($index)" type="button" class="botaoCancelaImg"><span
                aria-hidden="true">x</span></button>
    </div>
</fieldset>

Controller:

Promise.all(promises).then(fileContents => {
for (let index = 0; index < fileContents.length; index++) {
    $scope.modelCheckList.listImagens.push({ id, idCheckList, 'base64': fileContents[index], nome: nomeArq[index]})
}
});
