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
html code
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
