wp_enqueue_script not update my custom javascript code

Used WordPress:

Version 5.4

Problem:

I have this code inside themes function.php:

function kopiKupon() {
   wp_dequeue_script('customjs');
   wp_dequeue_style('custom');
	
   wp_enqueue_script( 'customjs', get_template_directory_uri() . '/assets/js/custom.js',array ('jquery'), '1.0',true );
	
wp_enqueue_style( 'custom', get_template_directory_uri() . '/assets/css/custom.css',false,'1.0','all');
}
add_action( 'wp_enqueue_scripts', 'kopiKupon' );

The problem is after i changing the custom.js code then upload it to server, the result is the new code is not applied

Question:

How to make the update code is working … ?

Answer:

Just change the version to false or raise it after changing the code

 wp_enqueue_script( 'customjs', get_template_directory_uri() . '/assets/js/custom.js',array ('jquery'), false ,true );

or raise the version

 wp_enqueue_script( 'customjs', get_template_directory_uri() . '/assets/js/custom.js',array ('jquery'), '1.1',true );
