AngularJS orderBy not working with trackBy - angularjs

Question

I don't know why orderBy is not working with trackBy, it is making me crazy :(
Here is my HTML code:
<div class="blocks-container" ng-init="loadProjects()" ng-controller="buildMonitorController">
<div class="row">
<!-- <div> -->
<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2 block animate"
ng-if="!errorDialogActive"
ng-repeat="build in builds.builds.build track by build._id | orderBy:'lastBuildDetails.startDate' : true"
ng-class="{'running': project.running ,'block-green': build._status ==='SUCCESS','block-red': build._status==='FAILURE'}"
id="{{build._id}}">
<div class="title-container"><p>{{build._buildTypeId}}</p></div>
<div class="update-container col-xs-12">
<time>{{ build.lastBuildDetails.startDate | date : 'dd.MM.yyyy H:mm:s'}}</time>
</div>
</div>
</div>
<!--</div>-->
<!-- Start error state dialog -->
<div ng-include src="'views/main/error-dialog.html'"></div>
Everytime give me the same result even if i change the order to reverse
And Here my AngularJS code:
$scope.refreshBuilds = function () {
$scope.errorList.length = 0
//#TODO remove this part right after the API is working
//Init
var suffix = '';
var randomnumber = Math.floor(Math.random() * 3);
//simulate mock by random number
switch (randomnumber) {
case 1:
suffix = '-success';
break;
case 2:
suffix = '-less';
break;
default:
break;
}
var url = 'mock/builds'+suffix+'.xml';
console.log('url: ' + url)
$http({
method: 'GET',
url: url,
headers: {
Authorization: 'Basic AAA'
}
}).success(function (data, status) {
//Recive builds from xml and reset scope
var buildsToFilter = new X2JS().xml_str2json(data);
$scope.errorDialogActive = false;
//filter builds which have a no build API detail status
if (buildsToFilter.builds.build !== undefined) {
angular.forEach(buildsToFilter.builds.build, function (build, index) {
$http({
method: 'GET',
url: 'mock/build-'+build._id+'.xml',
headers: {
Authorization: 'Basic AAA'
}
}).success(function (buildDetailData) {
$scope.errorDialogActive = false;
//push detail data into build array
buildsToFilter.builds.build[index].lastBuildDetails = new X2JS().xml_str2json(buildDetailData).build;
console.log(buildsToFilter.builds.build[index]);
}).error(function (data, status) {
$scope.errorDialogActive = true;
//remove build from index if no build detail was found
buildsToFilter.builds.build.splice(index, 1);
$scope.setError(status, '', '');
}).then(function () {
//after filtering builds to display, setup builds $scope for FrontEnd
$scope.builds = buildsToFilter;
});
});
} else {
}
}).error(function (data, status) {
//active dialog if error happens & set error
$scope.errorDialogActive = true;
$scope.setError(status, 'builds', '');
}).then(function () {
$timeout(function () {
$scope.finishedRequest = true;
}, 5000);
//refresh right after proceed and a little delay
$timeout(function () {
console.log('Starting refresh');
$scope.refreshBuilds();
}, 21000);
})
};
If You need more code please let me know

Try reading the docs. It doesn't appear you are using it correctly.
https://docs.angularjs.org/api/ng/filter/orderBy
The last argument can only be "reverse".
Move 'track by build._id' to the end of the expression (after orderBy).
ng-repeat="build in builds.builds.build track by build._id | orderBy:'lastBuildDetails.startDate'
