When I try to load options with an arrangement that has the format I leave you, the first option is blank and the following are the values of my arrangement. That's a problem for me when I try to select one other option I can not get the value.
<select ng-model='form.type'
ng-options="item.name for item in organizations"
ng-change="update({{form.type.id}})">
</select>
Format :
{"status":0,"Area":[{"id":"1","name":"Marketing","private":null},{"id":"2","name":"Ventas","private":null},{"id":"5","name":"Soporte","private":null}],"Count":3}
Controller :
$scope.organizations = data.Area;
What's happening in your case is that your ng-model variable, which is form.type, does not contain a value of your options in the select dropdown list. That's why you see an empty row. If you want it to be, for instance, the first one, you can do this (I changed to selected variable, but it doesn't matter at all):
$scope.organizations = [{"id":"1","name":"Marketing","private":null},{"id":"2","name":"Ventas","private":null},{"id":"5","name":"Soporte","private":null}];
$scope.selected = $scope.organizations[0].id;
Now, the selected variable has the id of your option. But that's not all. You also need to modify your HTML a bit, to have the ng-options have the id as your value. It can be anything you want in the object, not necessarily the id, but that's why I assumed you needed, you can change it:
<select ng-model='selected' ng-options="item.id as item.name for item in organizations" ng-change="update({{selected}})">
