Autofill html select AngularJS - html

Question

I have a little issue with a HTML select with AngularJS. When I do a petition to my API I get one of the values as an integer, but when I try to autofill a select with it I can't set de "value" correctly.
In this picture you can se what the HTML is receiving and the values that I want to set
Are there any way to cast this value?
Thanks in advance :)
EDITED:
The controller to get customer data and fill the form
.controller('CustomerDetailCtrl', ['Customer', '$scope', '$sessionStorage', '$stateParams', '$ionicPopup', function (Customer, $scope, $sessionStorage, $stateParams, $ionicPopup) {
if ($sessionStorage.auth) {
Customer.get({data: $stateParams.customerId + '_' + $sessionStorage.user_id}).$promise.then(function (data) {
if (data.response && $sessionStorage.role === 1) {
$scope.customer = data.response[0];
if (data.history) {
$scope.histories = data.history;
}
} else {
console.log('Error de accesso...');
}
})
}
$scope.addTask = function (customer) {
alert('add task!');
}
$scope.deleteTask = function (customer, history) {
alert('delete task!');
}
}])
The form:
<label class="item item-input item-select">
<div class="input-label">
Cliente avisado?
</div>
<select name="informed" ng-model="customer.informed" required>
<option value="0">NO</option>
<option value="1">SI</option>
</select>
</label>
And here a picture of the data from de API:

Answer 1

I know that you've already received an answer on this, but I wanted to show you one other potential option that doesn't involve having to change your data from an int to string. If you define the options for your select in your controller (or in a service if this will be used in multiple different places throughout your app) then you can take advantage of ng-options and its ability to use a value other than a string.
Here's an example (obviously I've hardcoded some things and put this all in a single module - not something you'd do in a real app).
JS:
angular.module('app', [])
.controller('ctrl', function($scope){
// select options (if these are common maybe store them in a service
// so you can share them in many controllers without duplicating the code)
$scope.selectOptions = [
{
text: 'NO',
value: 0
},
{
text: 'SI',
value: 1
}];
// sample data
$scope.customer = {
address: 'San Rosendo 11',
date: '2016-03-16T16:19:13+0100',
email: 'Montes',
equipment: 'PC',
id: 262,
informed: 1,
lastName: 'Montes',
location: 'Tienda',
name: 'Juanma',
notes: '',
pass: 'no tiene',
phone: '900112233',
price: '0',
status: 'Pendiente',
tasks: 'dfsdf'
};
});
HTML:
<div ng-app='app' ng-controller='ctrl'>
<select ng-model='customer.informed' ng-options='option.value as option.text for option in selectOptions'></select>
</div>

Answer 2

Define a default value somewhere in your controller: $scope.customer.informed = "NO";
