Javascript error from selecting a dropdown item

The item selected in this drop down affects the next drop down. The change triggers a Javascript call. I get this error when that happens. 

ExecuteCommand failed!
InError set by the client. Client Error:
System.InvalidOperationException: Javascript call [$(document.getElementsByTagName(\'select\')[3]).change();] failed! Please make sure the function exists and the call is using the correct prototype signature. Javascript error: [object Error]
