issue with header_textcolor and customizer

Hi!

I’m not sure if I’m posting this in the right category but was not allowed to post in advanced.

I got an issue with header_textcolor not rendering in the customizer.
It does not show me the changes until I save everything, everything else works. On the site it gets updated with the new color etc.

It does work if I change the wp_customize header_textcolor to default-text-color instead, but then I get an error in the customizer.

The code I’ve got is :

Customizer.php

function sj_customize_register( $wp_customize ) {
	$wp_customize->get_setting( 'blogname' )->transport         = 'postMessage';
	$wp_customize->get_setting( 'blogdescription' )->transport  = 'postMessage';
	$wp_customize->get_setting( 'header_textcolor' )->transport = 'postMessage';
}
add_action( 'customize_register', 'sj_customize_register' );

/**
 * Binds JS handlers to make Theme Customizer preview reload changes asynchronously.
 */
function sj_customize_preview_js() {
	wp_enqueue_script( 'sjalvservice_customizer', get_template_directory_uri() . '/js/customizer.js', array( 'customize-preview' ), '20151215', true );
}
add_action( 'customize_preview_init', 'sj_customize_preview_js' );

And in Customizer.js

// Header text color.
	wp.customize( 'header_textcolor', function( value ) {
		value.bind( function( to ) {
			if ( 'blank' === to ) {
				$( '.site-title a, .site-description' ).css( {
					'clip': 'rect(1px, 1px, 1px, 1px)',
					'position': 'absolute'
				} );
			} else {
				$( '.site-title a, .site-description' ).css( {
					'clip': 'auto',
					'position': 'relative'
				} );
				$( '.site-title a, .site-description' ).css( {
					'color': '#fff';
				} );
			}
		} );
	} );

Anyone got any insight on this?

Best Regards
