WP List Table Search box Not working - php

Question

I have implemented WP List Table to display my custom data. Data are displaying correctly. I have also implemented Sorting and Pagination
But Searching functionality not working.
When I enter values in textbox and submit it then it's redirecting me to ...wp-admin/edit.php
I have followed tutorials and has same code as they have.
This code is displaying Data and searchbox
$table = new AngellEYE_Give_When_Givers_Table();
$table->prepare_items();
echo '<form method="post">';
echo '<input type="hidden" name="page" value="ttest_list_table">';
$table->search_box('Search', 'givers_search_id');
$table->display();
echo '</form>';
Here is my Class that extends WP ListTable and Displays data.
class AngellEYE_Give_When_Givers_Table extends WP_List_Table {
public function __construct() {
parent::__construct( [
'singular' => __( 'Giver', 'angelleye_give_when' ), //singular name of the listed records
'plural' => __( 'Givers', 'angelleye_give_when' ), //plural name of the listed records
'ajax' => false //should this table support ajax?
] );

Any good way how can I fix that ?
Any information on this would be greatly appreciated. Thanks!
