Usually I use $(\"#id\").val() to return the value of the selected option, but this time it doesn\'t work. The selected tag has the id aioConceptName
$(\"#id\").val()
aioConceptName
If you want to grab the 'value' attribute instead of the text node, this will work for you:
var conceptName = $('#aioConceptName').find(":selected").attr('value');
