I'll see if I can replicate in JsBin.
Meanwhile I read the following thread: http://www.kendoui.com/forums/kendo-ui-mobile/tabstrip/can't-select-tabstrip-badge-and-update-it-.aspx
. I followed answer recommendation and moved code snippet to view class and updated reference from:
var tabstrip = $("#tabstrip").data("kendoMobileTabStrip");
var tabstrip = e.sender.view().footer.find(".km-tabstrip").data("kendoMobileTabStrip");
This worked. However, I need the snippet to be user-action-independent and view-independent thus I've placed it outside a view class (it's called on change of data source). Is there any more general or alternate way to get a reference?
