wp_enqueue_scripts dosen't work

function load_cdn_func() {
		wp_deregister_script('jquery');
		wp_enqueue_script('my-jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js', array(), '1.11.1');
}
add_action('wp_enqueue_scripts', 'load_cdn_func');

I wrote the code on functions.php.
But “http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js” wasn’t read.

add_action(‘wp_enqueue_scripts’, ‘load_cdn_func’);
↓　　↓
add_action(‘init’, ‘load_cdn_func’);
I changed like this, It’s OK.

Please teach me.
