i have a wizard with footer as
<footer>
<button name="create_invoices" id="create_invoice_open" string="Create and View Invoice" type="object" context="{'open_invoices': True}" class="btn-primary"/>
<button name="create_invoices" id="create_invoice" string="Create Invoice" type="object"/>
<button string="Cancel" class="btn-secondary" special="cancel"/>
</footer>
There are many methods with name create_invoices. Now i want to find which method from which module has been called.
