How to add POS Restaurant notes for every items into POS Restaurant reciept?

I manage to change the template for POS receipt on /addons/point_of_sale/static/src/xml/pos.xml which lies within :

<t t-name="PosTicket">

But how to change the detail on PosTicket ?

  <t t-name="PosTicket">

  .....

    <t t-esc="orderline.get_product().display_name"/>

???

I need to add the notes under the orderline.get_product().display_name. What should I write so it can show the notes?

I tried to add

<t t-esc="orderline.get_note()" />

But it seems doesn't work... Anybody know how to fix this?
