[javascript] How can I populate a select dropdown list from a JSON feed with AngularJS?

I have been looking hard for examples but could not find anything at all. The only thing I know is that I could use the http module to get my data. Here is what I am currently doing, but it's coded with Knockout. Can someone give me some advice on how I could recode this feature using AngularJS?

HTML

<select id="testAccounts" 
   data-bind="options: testAccounts, optionsValue: 'Id', optionsText: 'Name', optionsCaption: 'Select Account', value: selectedTestAccount">
</select>

Javascript

<script type='text/javascript'>
    $(document).ready(function () {

        var townSelect = function () {
        var self = this;
        self.selectedTestAccount = ko.observable();
        self.testAccounts = ko.observableArray();
        var townViewModel = new townSelect();
        ko.applyBindings(townViewModel);

        $.ajax({
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 },
            type: 'GET',
            success: function (data) {
                townViewModel.testAccounts(data);
            }
        });
    });
</script>

<select name="selectedFacilityId" ng-model="selectedFacilityId">
         <option ng-repeat="facility in facilities" value="{{facility.id}}">{{facility.name}}</option>
     </select>  

This is an example on how to use it.

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>
