angularjs - I'm having trouble with ngTableParams refreshing -

i can't seem figure out refresh. can intial load of page, when function getactivity() run doesn't update page. @ loss. tried many different things no success.

this code below being called factory

uaappcommon.tableparams = function(data,sortfieldorder){         var table = new ngtableparams({              //page: 1,            // show first page              count: data.length,          // count per page              sorting: sortfieldorder          }, {             counts: [],  //hides page sizes              total: data.length, // length of data              getdata: function($defer, params) {                  // use build-in angular filter                  var ordereddata = params.sorting() ?                                      $filter('orderby')(data, params.orderby()) :                                      data;                  $defer.resolve(ordereddata.slice((params.page() - 1) * params.count(), params.page() * params.count()));              }          });         return table;     }; 

this snippet calling function within controller.

$scope.getactivity = function(numdays){         appservice.loadactivity(numdays)         .then(function(response){             var activity = appservice.getactivity();             $scope.activitytable = appcommon.tableparams(activity,{date: 'desc'});           });     }; 

this html:

<table ng-table="activitytable" class="table" fixed-table-headers="scrollable-area">                             <tr ng-repeat="act in $data">                                 <td data-title="'date & time'" sortable="'date'">                                     {{act.date}}                                 </td>                                 <td data-title="'activity'" sortable="'activity'"> 

can provide plunker? can check line in controller $scope.activitytable = appcommon.tableparams(activity,{date: 'desc'}); try replacing $scope.activitytable = uappcommon.tableparams(activity,{date: 'desc'});

and if doesn't work reload table yourtablename.reload() after function gets called.
