Client-side validation: AssertThat vs Kendo NumericTextBox

[Furrman]

Dear jwaliszko,

I am trying to show error message on client side basing on Property with AssertThatAttribute. The issue is that I am doing it on Kendo control NumericTextBox and it does not work for it. I tested for ASP MVC TextBox control and there works fine. The message that I see on debugger is:
[info] (12:28:56): Dependency validation trigger - change event, handled.
expressive.annotations.validate.js:95 [info] (12:28:56): No fields dependent on detected.

Do you have any suggestion what I am missing?
I would be glad for your help.

Best regards,
Furrman
