Thank you for contacting our support services. I managed to reproduce the described by you behavior on all of the supported by AppBuilder mobile platforms. Unfortunately, this is expected as the data-binding is not supported in svg elements. This is a limitation that comes from Kendo UI. Still, as I am not sure why it is working in the AppBuilder simulator, I will pass it to the Kendo team for further investigation.
I hope this answers your question. Please, let me know if I can be of further assistance.
