[dhtmlx 4.1.2 grid] column move error

Suite and Optimus Suite 5
#1

An error when I move the grid’s header after an upgrade dhtmlx 4.1.2.

Your sample pages have the same problem too.
(http://dhtmlx.com/docs/products/dhtmlxGrid/samples/16_rows_columns_manipulations/13_pro_grid_moveCol.html)

Chrome’s console log :
Uncaught TypeError: undefined is not a functiondhtmlx.js:12 dhtmlXGridObject._showHContextdhtmlx.js:12
dhtmlXGridObject._onColumnMove

How can I fix it?
