New custom hook not displayed in the backend (1.7)

[Magnusvb]

First time with PrestaShop, so I'm not sure I'm doing it right.

I have registrated a new custom hook in the theme.yml file like this:

- name: displayMyCustomHook
        title: displayMyCustomHook
        description: Display my custom hook

Inside that hook I want to display the search bar. So the header.tpl have this code:

{block name='header_search'}
  <div class="header_search">
    {hook h='displayMyCustomHook'}
  </div>
{/block}

But, when going to Design > Positions in the backend, my custom hook is not displayed in the dropdown menu "Transplant to".

What am I doing wrong? Is this possible?

I have the same problem, resetting / changing the theme (removing shop1.json) doesn't fix the problem. I see only my custom hooks registered by modules, but not by theme. This is clearly a bug.
