double reaction on enter

Hello!
Faced such a problem.
After selecting a row in a datatable and pressing enter, I get a modal window with a form and also a reaction to the enter button, in which the form is validated.
The first time the form is shown, the validation happens automatically and shows an error, although the user did not press enter.
How to fix it?

  showAddToCheck(goods){
    webix.delay(this.addGoodsToCheck.show, this.addGoodsToCheck, [goods]);
  }

Thank you!!!
