Didnt work with HTML onchange="" property

So apparently I tried applying `onchange="Javascript()"` on my select. But it didnt work. An odd behaviour the dropdown didnt disappear once I select the element (normally it should vanish along my clicks) and the javascript script didnt run either.

Can anyone give me solution on this?

The issue names no file, test, or entry point. Start by reproducing the reported onchange behavior with a select enhanced by jquery-nice-select; completion would require identifying the relevant plugin behavior and verifying that the dropdown and handler work as expected.
