Remove js and css from a template in wordpress

I want to remove css and js file from a template in WordPress by using wp_dequeue_script and wp_dequeue_style function but my code is not working.

Js File: <script type='text/javascript' src='http://localhost/worpress/wp-content/themes/goliath/theme/assets/js/vendor/jquery.hoverintent.min.js'></script>

Css File: <link rel='stylesheet' id='plsh-bbpress-css'  href='http://ift.tt/1V5AFls' type='text/css' media='all' />

I am using goliath theme and I have added below code in goliath-child theme functions.php file

add_action('wp_print_scripts','example_dequeue_myscript');
function example_dequeue_myscript() {
   wp_dequeue_script( 'jquery.hoverintent' );
}

add_action('wp_print_styles','example_dequeue_mystyle');
function example_dequeue_mystyle() {
   wp_dequeue_style( 'bbpress' );
}

Please help me in these!
