In Kendo Grid for "GridEditMode.InCell" type Object values(Fields) of “[Bind(Prefix = "models")]IEnumerable” are always NULL

I have added all required attachments in appropriate order, I found out the problem, I have X Y Z columns and only Y is editable..

So X is a string type, If X contains string with character like '<' or '>' i am not able to edit that row, Rest of the rows i am able to edit.
