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
For good practice you need to use val() to get value of selected options not text().
val()
text()
Name choose io
You can use
$("#aioConceptName").find(':selected').val();
Or
$("#aioConceptName :selected").val();
I wish that helps ..
