Datasource runs previously cached nodeJS script.

Hello,

This is the second time this has happened to me so I guess there is a way to do this?  I have created multiple versions (upgrades) to a nodejs script which is stored in a directory mySqlScript. As seen in the example below my previous version was main.js. If I create a new datasourse and refer to a new script file in the same location i.e. main_v2.js the datasourse continues to use the old .js file i.e. main.js? is there something I am missing?
