<table>
<tr ng-repeat="i in questions | filter:search">

</table>
<script>
var app = angular.module('questionsApp', []);
app.controller('questionsController', function ($scope) {
$scope.questions = [{ "QuestionID": 1, "Answer": "koko", "AnswerID": null, "QuestionNumber": 1, "QuestionText": "koko Which language does Microsoft use to create apps", "test_id": "1", "theID": 1 }, { "QuestionID": 2, "Answer": "D", "AnswerID": null, "QuestionNumber": 2, "QuestionText": "Which of the following is not included in the Cs Language", "test_id": "1", "theID": 2 }, { "QuestionID": 3, "Answer": "A", "AnswerID": null, "QuestionNumber": 3, "QuestionText": "Which of the statements below is a proper method call for c", "test_id": "1", "theID": 3 }, { "QuestionID": 4, "Answer": "B", "AnswerID": null, "QuestionNumber": 4, "QuestionText": "In the WriteLine Method of the ", "test_id": "1", "theID": 4 }];
