Render template with context after creating objects - django

Question

Consider a textarea input to enter emails.
The view has a forloop: for each email the view tries to create a user. Then, if the user is created, I append it to my array "newUers", if the user already exists, I append it to the "alreadyUsers" array.
When the loop ends, I want to render a view with these arrays. But it does not work...
The users are correctly created but the view does not render the template.
Any idea?
invitations.html: a textarea with an an ajax call on submit
<div id="invitations">
<label>Enter your clients email</label>
<textarea v-model="invitations" class="textarea" id="invitations" name="invitations"></textarea>
</div>
<div>
<input id="send" type="submit" value="Save" #click="submit()">
</div>
user_invitation.js: the ajax call (based on Vue)
var vue = new Vue({
el: '#invitations',
data: {
invitations: '',
},
methods: {
submit: function () {
var self = this;
$.ajax({
type: 'POST',
url: '/accounts/invitations/create/',
data: {
invitations: this.invitations,
csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(),
},
context: this,
success: function () {
console.log("ajax success");
},
error: function () {
console.log("ajax error");
}
})
}
}
});

username=client,
email=client,
)
user.groups.add(Group.objects.get(name='Clients'))
user.save()
newUsers.append(client)
# Check if user already exists
except IntegrityError:
alreadyUsers.append(client)
return render(request, 'accounts/agent_invitations_confirmation.html',
