My client script to remove options from a choice list doesn't work as expected

[Jerome MAISETTI]

Hello
I added the option "4 - No Impact" with value 4 in the impact choice list.
I would like this option to be removed/added based on certain conditions.

I created the following client script to achieve this:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   //Type appropriate comment here, and begin script below
   var contract = g_form.getValue('u_service_contract');

    var serviceContractAjax = new GlideAjax('ServiceContractAjax');
    serviceContractAjax.addParam('sysparm_name', "getCSOCContract");
    serviceContractAjax.addParam('sysparm_service_contract', contract);
    serviceContractAjax.getXMLAnswer(getServiceTypeCallback);

    function getServiceTypeCallback(answer) {
        var getCSOCContract = answer;
        if (getCSOCContract == "false") { // OCD INTL Entity
            g_form.removeOption('impact', 4);
        }
    }
}

It removes it when I meet the condition, but it doesn't add it back when the condition is not matched.
I tried to add

else {

g_form.addOption('impact', 4);

}

but this only adds blank lines but not the expected value..

Thanks

Jérôme
