AngularJs

I have this angularjs controller

 angular.module('MyApp')  //extending angular module from first part
.controller('BudgetAndDetails', function ($scope, BDetail) { //explained    about controller in Part2
   $scope.budgetdetails = [];

   BDetail.GetBDetails().then(function (d) {
    $scope.budgetdetails = d.data;
});


   $scope.removeRow = function (item) {

    var index = $scope.budgetdetails.indexOf(item);
    if (index < 0) {
        $scope.budgetdetails.push(item)

    } else {
        $scope.budgetdetails.splice(index, 1)

    }


};

})

And I have written this json code in my C# controller

[HttpPost]
   public JsonResult update(BudgetandDetails budget)
   {
       var obj = _db.budgets.FirstOrDefault(b => budget.budget.idBudget == b.idBudget);

       _db.budgets.Remove(obj);


       _db.SaveChanges();


       return Json(obj, JsonRequestBehavior.AllowGet);


   }

How do I add the code in my angularjs controller to call the json when I delete a row?

What I have tried:

I have tried using $http in angularjs to call the json but I an not sure how to use it after deleting the row in the angularjs table.
