                }
            }

You have to write click event when Document Object Model (DOM) is ready.

Refer this

Just do it.

function addClickEvent() {
   $(document).on('click', 'btn_selector', function () {
      $(this).closest('tr').css("background-color", "#bbf6c5");
});

$(function () {
   addClickEvent();
  });
}

See, I have done this at my end.

Follow this step:

(1) routes

    Route::group(['prefix' => 'example'], function () {
        Route::get('', 'ExampleController@view');
        Route::get('get_table_data', 'ExampleController@get_table_data');
    });

(2) controller

    namespace App\Http\Controllers\User;

    use App\Http\Controllers\Controller;
    use DataTables;
    use App\Utility;

    class ExampleController extends Controller {

        public function view() {
            return view('pages.store_admin.example-table');
        }

        function get_table_data() {
            return DataTables::eloquent(Utility::query())->toJson();
        }

    }

(3) view

    @extends('layouts.store_admin')
    @section('title','Example')
    @section('page-title','Example')
    @section('page-title-desc','')
    @section('css')
    <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/v/bs/dt-1.10.15/datatables.min.css"/>
    @endsection

    @section('content')
    <div class="row">
        <div class="card">
            <div class="card-body"> 
                <div class="col-lg-12 col-md-12"> 
                    <div class="table-responsive">
                        <table class="table table-ordered" id="example_table" style="width: 100%">
                            <thead style="font-weight: bold;">
                                <tr>
                                    <td>ID</td>
                                    <td>Key</td>
                                    <td>Value</td>
                                    <td>Action</td>
                                </tr>
                            </thead>
                        </table>
                    </div>
                </div> 
            </div> 
        </div> 
    </div> 

    @endsection

    @section('js')
    <script type="text/javascript" src="https://cdn.datatables.net/v/bs/dt-1.10.15/datatables.min.js"></script>
    <script type="text/javascript">
