Limitation of javascript in sharepoint column name length

Problem Description:

My one of the SharePoint list column length is more than 30 characters (commented part in below image), but at the time of item updation it gives me error.

So i check with Debugger then i found column length mistake.

Because of JavaScript column length limitation if actual column name having more than 30 characters,it will take character maximum as 30 (see red circle in image).
