Inline script does not fire inside render_template in the WP Block Editor

Hi,

I have made a block and all is working ok except I added an inline script inside 'dc-carousel-block-template.php'. I tried running this but found this does not work. It works if I run it inside 'enqueue_script' or 'enqueue_assets'. Is there an issue running inline scripts? or is this just WordPress preventing it?

Block

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title'           => 'Carousel Block',
        'id'              => 'dc-carousel-block',
        'description'     => 'Carousel with product support',
        'type'            => 'block',
        'icon'            => 'screenoptions',
        'category'        => 'dc-blocks',
        'context'         => 'side',
        'render_template' => __DIR__ . '/template/dc-carousel-block-template.php',
...

inside 'dc-carousel-block-template.php'

<script>
document.addEventListener( 'DOMContentLoaded', function() {
    console.log('testing');
    //test();
});
</script>

Thanks
