I like to add a button on all listviews but this code is not working in the account.move module
<?xml version="1.0" encoding="UTF-8"?>
<template xml:space="preserve">
<t t-extend="ListView.buttons">
<t t-jquery="button.o_list_button_add" t-operation="after">
<button type="button" class="btn btn-secondary o_button_importpdf" accesskey="f">
Import Pdf
</button>
<input type="file" class="o_file_importpdf" style="display:none" accept=".pdf"/>
</t>
</t>
</template>
on other module the code is working, what do i miss?
