[Bug][ComboBox] Enabled adaptive rendering and custom values don't trigger onChange event

[Yanko-Georgiev]

Description

When using the ComboBox component with properties adaptive and allowCustom set to true, clicking on the "check icon" doesn't trigger the onChange event.

In version 11.0.0, the X button was substituted for a tick button, but the functionality is still as if the button only closes the ActionSheet.
