use ng-click directives , add appropriate handlers controller.

var foodapp = angular.module('foodapp', []);    foodapp.controller('foodctrl', function($scope) {    $scope.selectedrow = null;    $scope.fooditems = [{      name: 'noodles',      price: '10',      quantity: '1'    }, {      name: 'pasta',      price: '20',      quantity: '2'    }, {      name: 'pizza',      price: '30',      quantity: '1'    }, {      name: 'chicken tikka',      price: '100',      quantity: '1'    }];    $scope.setclickedrow = function(index) {      $scope.selectedrow = index;    }    $scope.moveup = function(num) {      if (num > 0) {        tmp = $scope.fooditems[num - 1];        $scope.fooditems[num - 1] = $scope.fooditems[num];        $scope.fooditems[num] = tmp;        $scope.selectedrow--;      }    }    $scope.movedown = function(num) {      if (num < $scope.fooditems.length - 1) {        tmp = $scope.fooditems[num + 1];        $scope.fooditems[num + 1] = $scope.fooditems[num];        $scope.fooditems[num] = tmp;        $scope.selectedrow++;      }    }  });
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>  <style>    .selected {      background-color: black;      color: white;      font-weight: bold;    }  </style>  <html>    <head>    <link href="css/bootstrap.min.css" rel="stylesheet" media="screen" />    <link href="css/bootstrap-theme.min.css" rel="stylesheet" media="screen" />  </head>    <body ng-app="foodapp" ng-controller="foodctrl">    <table class="table table-bordered" ng-keydown="key($event)">      <tr>        <th>#</th>        <th>name</th>        <th>price</th>        <th>quantity</th>      </tr>      <tr ng-repeat="item in fooditems" ng-class="{'selected':$index == selectedrow}" ng-click="setclickedrow($index)">        <td>{{$index}}</td>        <td>{{item.name}}</td>        <td>{{item.price}}</td>        <td>{{item.quantity}}</td>      </tr>    </table>    <button type="button" ng-click="moveup(selectedrow)">move up</button>    <button type="button" ng-click="movedown(selectedrow)">move down</button>    <div>      selectedrow = {{selectedrow}}    </div>  </body>    </html>
