This is fine, problem is probably somewhere else, in your HTML code.

Or … are you calling setupScript() function ?

<input id="call_response" value="Other"></div>
<script>
function setupScript() {
    OtherOnchanged('call_response', 'SPAN_Other', 'Other');
}

function OtherOnchanged (onChangedId, spanId, valueToCheck) {
    if ( $("#" + onChangedId).val() ==  valueToCheck) {
        alert ("Working");
    }
}
setupScript();
</script>
