### Bug report

When the Kendo UI NumericTextBox widget is implemented via the MVVM pattern, the property "selectOnFocus" can't be set with the 'data' attribute.

### Reproduction of the problem

1) Create a NumericTextBox widget by using MVVM pattern;

2) Set data-selectOnFocus="true" to the input element for the NumericTextBox;

3) Enter a value in the NumericTextBox and focus it;

4) The entered value is not selected;

A Dojo sample for reproduction: https://dojo.telerik.com/aTidozIC

### Expected/desired behavior

When the Kendo UI NmericTextBox with MVVM is configured with option data-selectOnFocus="true", the entered value should be selected, once the input element is focused.

### Environment

* **Kendo UI version:**2021.1.224
* **jQuery version:** 1.12.4
* **Browser:** [all]
