Hello

I am trying to add a new button in "editorbar", inheriting web_editor, but without having any result, this is my qweb code:

<?xml version="1.0" encoding="utf-8"?>
<templates id="template" xml:space="preserve">
    <t t-extend="web_editor.editorbar">
        <t t-jquery=".btn btn-primary btn-xs" t-operation="before">
            <span>OK</span>
            <a href="#" data-action="custom_action" class="btn btn-primary btn-xs">Custom Action</a>
        </t>
    </t>
</templates>

Can someone give me a hand, thank you.
