I am having trouble with my customize field in WordPress. The field shows up fine in the customize section of WP but it just does not echo out. 

    <p> <?php echo get_theme_mod('copyright_details'); ?> </p>

functions.php code:

	function limus_customize_register( $wp_customize )
	{
	   //copyright
		$wp_customize->add_section('limus_copyright', array(
			'title' => __('Copyright Details', 'limus'),
			'description' => 'Add/Edit copyright information'
		));
		$wp_customize->add_setting('copyright_details', array(
			'default' => '&copy; 2000-2013 Limus Design Inc. All Rights Reserved.'
		));
		$wp_customize->add_control('copyright_details', array(
			'label' => __('Copyright Information', 'limus'),
			'section' => 'limus_copyright',
			'setting' => 'copyright_details'
		));
	}
	add_action( 'customize_register', 'limus_customize_register' );
