ch cell does not react on click when using internet explorer

I have a grid with a ch column. All the browsers except internet explorer work fine when i click the checkbox. But unfortunatelly when i test with internet explorer and try to click the checkbox it does not react ( event is not fired and it doesnt change to clicked )

Any solution?

P.S. I am using dhtmlx 3.6

Unfortunately the issue cannot be reproduced locally.
the following sample works well for me:

If the issue still occurs for you, please provide with a complete demo/demo link, wheer the issue can be reconstructed.
