Stepper Doesn't Have A Destroy Method?

[TheBigK]

I was trying to get the stepper to work with the CloneYa plugin and I guess have discovered a bug. While I'm not an expert in jQuery; I was told that the stepper doesn't have a destroy method. For details, please have a look at the following issue: https://github.com/yapapaya/jquery-cloneya/issues/55 and the jsFiddle that fixes the issue: https://jsfiddle.net/bwyu6c8v/3/
