form submit button enable disable

Hi Webix team,

In this snippet - https://snippet.webix.com/wldpbvmi

If I am changing the combo value submit button enable disable properly, but if I am changing the input box value at that time first I need to blur input box first then only I can see the submit button enable disable.
Also how to do validation for space in input box in for loop.

Hello,
You can use onTimedKeyPress which fires after typing has been finished in the field.
