Composer autoload classmap in CI 3.0

I have tried to use autoload class map to autoload aplication/models folder

Code:

"autoload": {

"classmap": [
"application/models"
]
}

but it does not work if i dont dump-autoload everytime after creating a new file. What is the hack? 

That's how composer works. http://stackoverflow.com/questions/25619...-in-folder
