Special Character issue in grid columns

[rsgmedia]

We are facing a strange issue in grid. In a simple editable column when user enters the following string ">?Test:001"_Live{Test-01} and comes out of the textbox it gets repeat in the cell.

How can we fix it?

I'm not able to reproduce the mentioned issue. I checked by entering the mentioned string in this example: http://paramquery.com/pro/demos/grid_json but there is no issue of repetition.

Can you please share a jsfiddle or sample code which can demonstrate the issue.

Issue was at our end. We are using render to show title on cells and there it was breaking due to '>' sign.
