I create my own module to do a qweb custom report for Quotation.

If I change the standar qweb report for quotation report type from PDF to HTML Odoo shows the Editor capabilities that allows to modify the template (add images and so on), but if I do the same on my custom qweb report doesnt show up those buttons.

So, when I show up in html mode the website edition controls are missing.

How to show website edition controls on my own quotation templete module?
