How to use jsr223 variables in loop controller in jmeter

I have created a list of lists in jsr223 preprocessor and want to run a loop for size of list and print the elements in list in post processor inside the loop. But i am unable to use the count variable in loop controller.

The end result i need is in first iteration of loop [1,2,3,4,5] second iteration [6,7,8,9,10]

at present im getting no output because loop controller is not reading count variable.
