Uncaught TypeError: extender is not a function

I'm trying to implement DataTable editor in my application and currently facing issue> Uncaught TypeError: extender is not a function whenonBlur: 'submit'is called.
When I tried to debug the lib I found out that there is no function _fnExtend which makes var extender = $[O12][J3p][u12][o3p]; extender undefined.
