The config parameter can have the following values:

• "user" - if the change was made by user
• "auto" - if the change was made by the library inner logic
• undefined - if the change was made by a control's setValues method call made by a programmer.

Also, you can get a custom value as the config parameter. To do that call the setValues method passing your value as the last argument:

webix.ui({
  view:"form",
  // ..config
  on:{
    onChange: function(newValue, oldValue, config){
        // config is {yourProperty: "yourValue"}
    }
  }
});
 
// onChange event will receive object as the last parameter
$$("$form1").setValues(values, true, {yourProperty: "yourValue"});
