Angularjs, Applying Action on Selected Checkboxes in Table

Im trying to Learn AngularJS and im implementing this Checkboxes that when i some checkboxes from the Grid and click the Remove Button then the Data from Table Should Be removed of Selected CheckBoxes.

I tried but cant figure out how to implement it.

Please see my this code on Plunker. http://plnkr.co/edit/e7r65Me4E7OIWZ032qKM?p=preview

It would be nice, if you fork and Give Working Example of the Above Plunker.

An easy way would be to change your students list to:

$scope.students = [
  {Rollno: "1122",Name: "abc",Uni: "res", selected: false},
  {Rollno: "2233",Name: "def",Uni: "tuv", selected: false},
  {Rollno: "3344",Name: "ghi",Uni: "wxy", selected: false}
];

with:

<input type="checkbox" ng-model="student.selected">

in the view. With injecting filter into the controller, you can then rewrite the remove function to:

$scope.remove = function(){
  $scope.students = filterFilter($scope.students, function (student) {
    return !student.selected;
  });
};

here is full code:

(function (app, ng) {
  'use strict';

  app.controller('TableCtrl', ['$scope', 'filterFilter', function($scope, filterFilter) {
    $scope.students = [
      {Rollno: "1122",Name: "abc",Uni: "res", selected: false},
      {Rollno: "2233",Name: "def",Uni: "tuv", selected: false},
      {Rollno: "3344",Name: "ghi",Uni: "wxy", selected: false}
    ];

    $scope.save = function(){
      $scope.students.push({
        Rollno: $scope.new_rollno,
        Name: $scope.new_name,
        Uni: $scope.new_uni
      });

      $scope.new_rollno = $scope.new_name = $scope.new_uni = '';
    };

    $scope.remove = function(){
      $scope.students = filterFilter($scope.students, function (student) {
        return !student.selected;
      });
    };
  }]);
}(angular.module('app', []), angular));
