Nevermind i found where was bug.
$scope.exampleArray = [];
$scope.pushInArray = function(id) {
// get the input value
/* var inputVal = id;*/
//$scope.exampleArray.push(id);
var index = $scope.exampleArray.indexOf(id);
console.log(index);
if(index === -1 ){ //this is where i have bug. match the condition with -1
$scope.exampleArray.push(id);
} else { $scope.exampleArray.splice(index, 1);}
$scope.deleteBulk = function(){
if(confirm("Are you sure you want to delete " + $scope.exampleArray.length + " record(s))?")){
$http.post('http://localhost/angular-code-crud/index.php/user/bulk_delete_user',
{'id':$scope.exampleArray}).success(function(){
$scope.displayUsers();
});
}
};
};

Hope this helps
JS :
$scope.pushInArray = function(data) {
var index = $scope.exampleArray.indexOf(data.id);
if(data.checked) {
if( index === -1 ) {
$scope.exampleArray.push(data.id);
}
} else {
$scope.exampleArray.splice(index, 1);
}
}
HTML : change input type="checkbox" line to below
<input type="checkbox" name="arrExample" ng-model="user.checked" ng-change='pushInArray(user)' >

change condition index
$scope.pushInArray = function (id) {
var index = $scope.exampleArray.indexOf(id);
if (index <= -1) {
$scope.exampleArray.push(id);
} else
$scope.exampleArray.splice(index, 1);
};
};
