Most likely, the second parameter to an on  function (or possibly getAttrs ) has a problem. Could you share your sheet workers?

I have fixed the problem by changing the order of declaration: 1. var functioname = function(){ .... 2. on(events, functionname); I just wanted to understand what the error exactly means. Thank you, I guess your answer sufficiently answers that.
