How to use two different forms of Django in one template?

My forms.py:

class AlertForm(forms.ModelForm):
class Meta:
    model=Alert
    fields = ('high','medium', 'user')
    widgets = {
        'user':  forms.HiddenInput()
    }

AlertCountFormset = modelformset_factory(Alert,
                                       form = AlertForm)

Another Django Form class:

class NotifierForm(forms.ModelForm):
high = forms.ChoiceField(choices=NOTIFIER_TYPE)
medium = forms.ChoiceField(choices=NOTIFIER_TYPE)
low = forms.ChoiceField(choices=NOTIFIER_TYPE)  

def save(self, commit=True):
    alert = super(NotifierForm, self).save(commit=False)
    alert.high = self.cleaned_data["high"]
    alert.medium = self.cleaned_data["medium"]
    alert.low = self.cleaned_data["low"]
    alert.save()
    return alert

class Meta:
    model=Notifier
    fields = ('high','medium', 'low', 'user')
    widgets = {
        'user': forms.HiddenInput()
    }

NotifierFormset = modelformset_factory(Notifier,
                                    form = NotifierForm)

Below for the selection fields:

NOTIFIER_TYPE = (
(0, _('E-mail')),
(1, _('Skype')),
(2, _('IRC'))
)

I want to fill out these two forms with the same template. Therefore, I prefer to write the same views for both:

def profile_setting(request, slug):
if request.method == 'POST':
    alert_form = AlertForm(request.POST)
    notifier_form = NotifierForm(request.POST)
    if alert_form.is_valid() and notifier_form.is_valid():
        alert = alert_form.save(commit=False)
        notifier = notifier_form.save(commit=False) 
        alert.user = request.user.username
        notifier.user = request.user.username
        notifier.save()
        alert.save()
        return HttpResponseRedirect(reverse('profile_setting', args=[slug]))

extra_context = {
    'alert_form': AlertForm(),
    'notifier_form': NotifierForm()
}
return direct_to_template(request,'users/user_profile_setting.html',
                          extra_context)

Accordingly, in my template.html:

{% block content %}
<h3>{% trans "Alerts limit" %}</h3>
<form action="" method="POST">{% csrf_token %}
    {{ alert_form.as_p }}
    <input type="submit" value="{% trans 'Update' %}" />
</form>

<h3>{% trans "Notifier setting" %}</h3>
<form action="" method="POST">{% csrf_token %}
    {{ notifier_form.as_p }}
    <input type="submit" value="{% trans 'Update' %}" />
</form>

Everything is correct, it also saves the data in the database. But the problem occurs whenever I fill out the aler_form and click on the refresh button. it also updates another form with the same value or vice versa. For example, if I choose

1 2 3 for high , medium and low for alert_Form

Then it also saves the same value for notify_form. Why is this happening. Is this something wrong with the views?
