oboejs : Nothing happens after JSON response

JS:

function OrderFormController($scope, $http) {

$scope.sampleJSON = [];
$scope.sampleJSONDuplicates = [];
oboe('/getPMDResultsByDateAndSeverity')
   .done(function(data) {
    $scope.sampleJSON.push(data.pmdStructureWrapper);
    $scope.sampleJSONDuplicates.push(data.pmdDuplicates);
   })
   .fail(function() {

      console.log('error');
   });

}

</body>

the page does not render anything. Is there something I am missing? I know the page renders before the result, but how do I re-render it? I have to keep it async because when I host my app in heroku the call gets timed out(30000ms),if I use async false from ajax:

var jsonData = $.ajax({
        url: "/getPMDResultsByDateAndSeverity",
        dataType: "json",
        crossDomain: true,
        async: false
    }).responseText;

Also it keeps running out of heap memory as when I use async false. I have modified the server side to perform at optimal level. When using async false : c.****.algo.MetadataLoginUtil : Total Time Taken 26825

After using async true : which I thing oboe.js internally does:

c.****.algo.MetadataLoginUtil : Total Time Taken 6321

The above is the time taken is for getting response from server side.

Solution

You need to call $scope.$apply() at the end of done().

Because the call is async and oboe does not hook into angular's scope framework, angular will not know that the page needs to be re-rendered after you have received the ajax response.

$scope.$apply() tells Angular that the scope has changed and to therefore refresh the page display. This question and answer explains this in more detail.
