Why different scopes for my elements?

I am relatively new to AngularJS. I have to populate a list using a result of the Ajax call, but I have checked that the elements are in different scope.

   <ng-form class="ng-dirty ng-valid ng-valid-required" name="fleetForm">
    <a target="_blank" href=".....">Click to verify your log type.</a>
    <select class="ng-dirty ng-valid ng-valid-required" required="" ng-options="...." ng-model="test.fleet">
    <fg-test-widget class="ng-isolate-scope ng-pristine ng-valid" ng-model="test-model" horizontal="false">
</ng-form>
