Onchange client script when a field changes

[Deepthi13]

Hi team,

(i have couple of other validations so i am writing client script instead of ui policy)

i am trying below script on onchange on emptype field, it is working fine for both if condition. 

1. But when i change value to "employee" i am getting alert inside 1st if condition, and form looks like below
2. When I change to “consultant” I am getting alert in second if condition but it does not hide the fields still remains same on form please suggest. 

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var emptype = g_form.getValue('employement_type');
if(emptype=='employee'){
alert('onchange employee'+emptype);
g_form.setDisplay('candidate_id',true);
g_form.setDisplay('u_employee_id',true);
g_form.setMandatory('candidate_id',true);
g_form.setMandatory('u_employee_id',true);
}

if(emptype=='consultant'){
alert('onchange consultant'+emptype);
g_form.setDisplay('candidate_id',false);
g_form.setDisplay('u_employee_id',false);
g_form.setMandatory('candidate_id',false);
g_form.setMandatory('u_employee_id',false);
}
//Type appropriate comment here, and begin script below

}

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var emptype = g_form.getValue('employement_type');
if(emptype=='employee'){
alert('onchange employee'+emptype);
g_form.setDisplay('candidate_id',true);
g_form.setDisplay('u_employee_id',true);
g_form.setMandatory('candidate_id',true);
g_form.setMandatory('u_employee_id',true);
g_form.clearValue('candidate_id',true);
g_form.clearValue('u_employee_id',true);
}

if(emptype=='consultant' || emptype=='none'){
alert('onchange consultant'+emptype);
g_form.setMandatory('candidate_id',false);
g_form.setMandatory('u_employee_id',false);
g_form.setDisplay('candidate_id',false);
