This bug is visible in your demo at http://demos.kendoui.com/web/grid/editing.html.

in Grid / Batch editing when you enter a decimal value in column Units in Stock, then click "Save changes"
page does not save the value and the page does not do any saving.

perhaps there is a bug in NumericTextBox which exists in function caret(element, position)
We get an unspecified error for this bug in our project
