Does DatePicker must have a onChange handler?

I am trying to use DatePicker but I can't type the day portion of the date it doesn't emit any errors or warnings here is my code below....

any ideas??

01.const SingleDate = ({ label, required, name, ...props }: ISingleDate): React.ReactElement => {

02. return (

03. <div className="erp-input-date">

04. <label className="k-form-field" data-cy={name}>

05. <span>{label}</span>

06. {required && <span className="erp-field-required">*</span>}

07. <DatePicker

08. {...props}

09. name={name}

10. format="dd/MM/yyyy"

11. formatPlaceholder={{ year: "ano", month: "mes", day: "dia" }}

12. />

13. </label>

14. </div>

Hello, Joao Paulo,

The KendoReact DatePicker has controlled and uncontrolled modes. The onChange handled is required in controlled mode(when value is set). When defautlValue is set, the component is in uncontrolled mode and the onChange handler is not needed:

I hope this will help to achieve the desired result.
