Issue in Inserting Formula type column to the Grid

if i insert a column to the grid that is formula type like( ‘ed[=c1+c2]’, it throws an JS error as this.cells3(…) is null or not an object but i could able to insert normal editable column into my grid. Please let me know how to fix this

Add Column

Thanks in advance

Please, try to use the:

<button onClick="newcreateBOM.insertColumn(newcreateBOM.getColumnsNum(),'test1','ed[=c1+c2]',100);">Add Column</button>
