Where to add action.setRedirectedURL(current) in client callable UI action.

[Obito]

Hi all, My client callable UI action is being redirected to other page. I used action.setRedirectURL(current) but it is still being redirected to other page. Please refer below code.

function doIt() {
    if (confirm("Are you sure")) {
        //alert("You clicked yes");
        gsftSubmit(null, g_form.getFormElement(), 'populate');
    }
}

if (typeof window == 'undefined')
    updateRecord();

function updateRecord() {
    var inputs = {};
    inputs['table_name'] = 'incident';
    inputs['incident'] = current;
    // Start Asynchronously: Uncomment to run in background.
    sn_fd.FlowAPI.startFlow('global.Test Inc', inputs);
    action.setRedirectURL("https://dev223110.service-now.com/incident.do?sys_id=57af7aec73d423002728660c4cf6a71c");
    // Execute Synchronously: Run in foreground.
    //sn_fd.FlowAPI.executeFlow('global.[internal name of flow]', inputs);
}

The others have shown you THAT its a server side script, but not why.
The setredirect is in preparation for after the database transaction, and is thus not client side.
