different price.php for category

Hello,
I’m trying to add custom templates for different categories. I included the following code in my single-product php:

<?php if ( has_term( 'CATEGORY', 'product_cat' ) ) {
    woocommerce_get_template_part( 'content', 'single-product-CUSTOM' );
} else {
    woocommerce_get_template_part( 'content', 'single-product' );
} ?>

it works well so far. But now I want to edit the part wich contains the price information. This is included with the following hook:

do_action('woocommerce_single_product_summary');

which referes to price.php
I created a new file called pricecustom.php. But I don’t know how to show the pricecustom.php on the new single-product-CUSTOM page

hope u can help me
