Node.js datatables editor - Filter select option depending on a certain value

I'm using the node.js datatable editor library. When trying to filter the select options depending on a specific user_id ... I'm getting TypeError: this.where is not a function

I already posted the issue on SO ... https://stackoverflow.com/questions/54012451/node-js-datatables-editor-filter-select-option-depending-on-a-certain-value

How do I get to filter the option values in editor for node.js?
