I keep getting Failed lookup for key [form] in u'(...) when I click submit button. I cant figure whats is happening or why. I dont know if is crispy, form or views problem. Maybe a tip is that i put extra=1 in formset but only shows 1 line.

If you want to handle 2 or more forms in the same template ant put the submit button outside the forms, you have to remove the form tag:
self.helper.form_tag = False
