Add not inserting/working

Question

I have an AccountRegister model that i make into an Account model and then add that Account model to the database. There is zero errors/exceptions when i click the create button, it just redirects to index as if it has inserted into the database, but it has not.

The reason why i use AccountRegister model is that i want the user to enter password and email twice.

I hope someone can help with this.
