How to enable ng-options inside ng-repeat?

I'm trying to use ng-options inside ng-repeat, but seems I'm missing something bwcause I do not see any values populated into the select control.

Here is the html code:

<div ng-controller="testCtrl">
    <table border="1" style="width:300px">
        <tr>
        <th>id</th>
        <th>name</th>
        <th>age</th>
        <th>select</th>
        </tr>
        <tr ng-repeat="person in persons">                        
            <td>{{ person.id }}</td>
            <td>{{ person.name }}</td>
            <td>{{ person.age }}</td>               
            <td>
            <select ng-model="person.chosenNumber" ng-options="suggestion.number as suggestion.destination for suggestion in person.suggestedPhones"></select>
            <button ng-click="showSelected()">Ok</button>
            </td>
        </tr>        
    </table>
</div>

Js code:

var testModule = angular.module('myApp', []);

function testCtrl($scope) {                      

$scope.persons = [
    {'id': 1, 'name': 'omer', 'age': 35,  'suggestedPhones': {'destination': 'home', 'number': '0544317259'} },
    {'id': 2, 'name': 'noam', 'age': 32, 'suggestedPhones': {'destination': 'home', 'number': '036024607'} },
    {'id': 3, 'name': 'dafna', 'age': 28, 'suggestedPhones': {'destination': 'home', 'number': '0522318779'} }
]

$scope.showSelected = function () {
    alert(1);       
}
}

HTML:

<div ng-controller="testCtrl">
    <table border="1" style="width:300px">
        <tr>
        <th>id</th>
        <th>name</th>
        <th>age</th>
        <th>select</th>
        </tr>
        <tr ng-repeat="person in persons">                        
            <td>{{ person.id }}</td>
            <td>{{ person.name }}</td>
            <td>{{ person.age }}</td>               
            <td>
            <select ng-model="person.chosenNumber" ng-options="suggestion.number as suggestion.destination for suggestion in person.suggestedPhones"></select>
            <button ng-click="showSelected($index)">Ok</button>
            </td>
        </tr>        
    </table>
</div>

Javascript:

var testModule = angular.module('myApp', []);

function testCtrl($scope) {                      

$scope.persons = [
    {'id': 1, 'name': 'omer', 'age': 35,  'suggestedPhones': {'destination': 'home', 'number': '0544317259'} },
    {'id': 2, 'name': 'noam', 'age': 32, 'suggestedPhones': {'destination': 'home', 'number': '036024607'} },
    {'id': 3, 'name': 'dafna', 'age': 28, 'suggestedPhones': {'destination': 'home', 'number': '0522318779'} }
]

$scope.showSelected = function (data) {
    alert($scope.persons[data].chosenNumber);       
}

Either the suggestedPhones is wrong (should be array) or you should use the label for (key , value) in object (ref) variant of ng-options. Try the following, if it is indeed what you want:

$scope.persons = [
    {'id': 1, 'name': 'omer', 'age': 35,  'suggestedPhones': [{'destination': 'home', 'number': '0544317259'}] },
    {'id': 2, 'name': 'noam', 'age': 32, 'suggestedPhones': [{'destination': 'home', 'number': '036024607'}] },
    {'id': 3, 'name': 'dafna', 'age': 28, 'suggestedPhones': [{'destination': 'home', 'number': '0522318779'}] }
]

(The suggestedPhones have become arrays.)

(UPDATE RELEVANT TO COMMENT) Getting the selected person and phone data is as simple as:

<button ng-click="showSelected(person)">Ok</button>

And in the JS:

$scope.showSelected = function (person) {
    console.log(person);        
}
