Perfect, it works. :)

SampleForm(Form):
     text = TextField()

form = SampleForm(text='Default Value')

It should be noted that `formdata` and `obj` take precedence over
`**kwargs`. The order of precedence is `formdata` -> `obj` ->
`**kwargs`. To update an obj the `populate_obj` method is also quiet
handy. It loops through each of the fields in the form and calls
setattr(obj, field, value).
