Hi Nicky,
You just need to return the submit_text you want to use from your
method, then in the form display do something like this:
form.display(submit_text)
Tip of the day:
If you print form.template_vars you get something like:
["action", "method", "form_attrs", "submit_text", "table_attrs"]
every attribute listed in the template_vars of a widget can be changed
by passing it at __init__ and also at display, since submit_text is
there the solution I mentioned should will work.
Hope this helps.
Ciao
Michele
