grid.dataItem(row); returns null in IE10

[Craig]

Hi there!

The following code returns null in IE10 but returns values in Chrome and Firefox.

var grid = $("#saleGrid").data("kendoGrid");
row = grid.select();
item = grid.dataItem(row);

I have debugged the internal method and I have found that there is data there. But for whatever reason I am getting null values in IE.
I have attached a screencast to highlight the issue fully.

Weird, I renamed the variable to something else and this started working.

I must have a global someplace that's causing this error. I'm still open to ideas on tracking down the culprit.

Thanks!
