Cache model based on schema title is flawed

[chidam333]

Describe the bug

I had a user model as a schema inside my reqbody but i need to extend the schema so i extended it using runtime creating model methods. For my surprise it was not having any effect. Only then did i figure out that you guys are caching models based on schema title. This is not intuitive. I am happy to hear what was the logic behind it ?
