Custom checkbox

Checkbox appears in add form, and in search form. But it does not search, when i set “One” or “Two”. May be i made mistake, all code is:

add_filter( "adverts_form_load", "my_adverts_form_load" );
	
	function my_adverts_form_load( $form ) {
	
	if( $form["name"] != "advert" ) {
	return $form;
	}
		$form["field"][] = array( 
	"name" => "my_custom_checkbox",
	"type" => "adverts_field_checkbox",
	"order" => 2,
	"label" => "Custom Checkbox",
	"is_required" => false,
	"validator" => array( ),
	"max_choices" => 2,
	"options" => array(
	array("value"=>"1", "text"=>"One"),
	array("value"=>"2", "text"=>"Two"),
	)
	);
	
	return $form;
	}
add_filter( 'adverts_list_query', 'search_by_custom_checkbox_query' );
function search_by_custom_checkbox_query( $args ) {
    if( ! adverts_request( "my_custom_checkbox" ) ) {
        return $args;
    }
    $args["meta_query"][] = array(
        'key'=> "my_custom_checkbox", 
        'value'=> adverts_request( "my_custom_checkbox" ), 
        'compare'=> 'LIKE'
    );
    return $args;
}
add_filter( 'adverts_form_load', 'search_by_custom_checkbox' );
function search_by_custom_checkbox( $form ) {
    
    if( $form['name'] != 'search' ) {
        return $form;
    }
    $form['field'][] = array(
        "name" => "my_custom_checkbox",
        "type" => "adverts_field_checkbox",
        "order" => 20,
        "label" => __("Category", "adverts"),
        "max_choices" => 10,
        "options" => array(
            array("value"=>"1", "text"=>"One"),
            array("value"=>"2", "text"=>"Two"),
        ),
        "meta" => array(
            "search_group" => "visible",
            "search_type" => "full" 
        )
    );
    return $form;
}
