If what you need is to define default values for the new forms that are created you can redefine the empty_form property of a InlineFormSet:

class MyDefaultFormSet(django.forms.models.BaseInlineFormSet):
    @property
    def empty_form(self):
       form = super(MyDefaultFormSet, self).empty_form
       # you can access self.instance to get the model parent object
       form.fields['label'].initial = 'first name'
       # ...
       return form

 class DetailsInline(admin.TabularInline):
    formset = MyDefaultFormSet

Now, every time you add a new form it contains the initial data you provided it with. I've tested this on django 1.5.
