Onchange native event does not trigger after click the clear button

Question

Hi!I have been working with the DatePicker component and since there is no mask in this component and I want to be able to type dates without format I mean I can type 10081994 and this will be valid cause I am getting this value in onchange native event and parsing it to a valid DateTime. (I attach the project sample).It works but I notice when I clear the input with the clear button in the DatePicker and later enter a flat string (10081994) the onchange event is not fired so the flat string is not parsed to a DateTime value. This happens in 19.1.0.59 version if you downgrade the version to 18.2.0.55 it works, I did not check the other versions because I realized this for a casualty cause I have an old project with the 18.2.0.55 version but in my current project, I am with 19.1.0.59 version and is happening in the last version as well.Attached two gif's with the different versions and the sample project.I appreciate your answer!Attachment: Desktop_bb0d75d6.rar

Hi there.In the "19.1.69" version the bug is fixed, but updating the version to "19.2.44" The bug is still present. You can reproduce it by updating the demo project you attached in your answer updating it to "19.2.44"

. The issue is when you cleared the date with x button onChange is fired but when you enter a new value onChange is not fired so the value is not parsed.
