angular, try to display object in ng-repeat fails - angularjs

Question

i'm writing an mobile application in javascript with angularJS and ionicframework (last beta v.11), i create dinamically an object and want to display all objects inside in a ng-repeat. Why nr-repeat don't display anything?
This is screen from my object:
I use this code for put values in scope:
$scope.distanceSuppliers = myCar;
And this is the code in html:
<ion-item ng-repeat="(id, supplier) in distanceSuppliers">
<div class="items item-button-right" ng-click="openDetails(id)">
{{supplier.name}}<br />
{{supplier.address}}<br />
</div>
</ion-item>
This is my complete code for JS:
.controller('suppliers', function($scope, cw_db, $ionicPopup, $ionicActionSheet, appdelegate, $rootScope, $firebase, $location, $ionicLoading, cw_position) {
$ionicLoading.show({
template: 'Updating data..'
});
var geocoder;
var tot = 0;
var done = 0;
geocoder = new google.maps.Geocoder();
cw_db.getData(cw_db.getSuppliers(), "", function(suppliers) {
cw_position.getPosition(function (error, position) {
suppliers.on('value', function(supp) {
$scope.distanceSuppliers = {};
tot = 0;
done = 0;
supp.forEach(function(childSnapshot) {
tot++;
var childData = childSnapshot.val();
if (childData.address) {
calculateDistance(childData, position.coords.latitude, position.coords.longitude);
}
});
});
$ionicLoading.hide();
});
});
function calculateDistance(childData, usrLat, usrLon) {
var service = new google.maps.DistanceMatrixService();
service.getDistanceMatrix(
{
origins: [new google.maps.LatLng(usrLat, usrLon)],
destinations: [childData.address],
travelMode: google.maps.TravelMode.DRIVING,
unitSystem: google.maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, function(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
alert('Error was: ' + status);
} else {
done++;
var results = response.rows[0].elements;
childData.distance = results[0].distance.value;
$scope.distanceSuppliers.push(childData);
if (done == tot) {
console.log($scope.distanceSuppliers);
}
}
});
}
$scope.openDetails = function(index) {
//appdelegate.setCallId(index);
//$location.path("/app/supplierDetails");
}
})
what's wrong?

Not sure, but I believe you have a data binding update problem.
Try using the $timeout to force the render:
w_position.getPosition(function (error, position) {
$timeout(function() {
suppliers.on('value', function(supp) {
$scope.distanceSuppliers = {};
tot = 0;
done = 0;
supp.forEach(function(childSnapshot) {
tot++;
var childData = childSnapshot.val();
if (childData.address) {
calculateDistance(childData, position.coords.latitude, position.coords.longitude);
}
});
});
$ionicLoading.hide();
});
});
And don't forget to add the $timeout parameter to the controller:
.controller('suppliers', function($scope, ...<other parameters here>..., $timeout) {

I found the problem! Fix using $scope.$apply();
The problem was that i was writing in a different $scope using this code:
cw_position.getPosition(function (error, position) {
suppliers.on('value', function(supp) {
tot = 0;
done = 0;
supp.forEach(function(childSnapshot) {
tot++;
var childData = childSnapshot.val();
if (childData.address) {
calculateDistance(childData, position.coords.latitude, position.coords.longitude);
}
});
});
$ionicLoading.hide();
});
where cw_position.getPosition call a js with this code:
angular.module('cw_position', [])
.service('cw_position', function() {
this.getPosition = function(callback) {
navigator.geolocation.getCurrentPosition(
function (position) {
return callback(null, position);
},
function(error) {
return callback(error, null);
}
);
}
// Built google maps map option
//
this.getGoogleMapOptions = function (lat, lon, zoom, type) {
if (type == null) {
type = google.maps.MapTypeId.ROADMAP;
}
var mapOptions = {
center: new google.maps.LatLng(lat, lon),
zoom: zoom,
mapTypeId: type
};
return mapOptions;
}
});
navigator.geolocation.getCurrentPosition causes the 'problem'
Thx to all for your help
