Programatically enable Content Approval (Moderation) in SharePoint List

I am writing a app that creates a custom events list.

I'd like to enable content approval (also referred to Moderation on the back end) upon creation of the list.

Here's what my list-creation code looks like.

    function createList(listToCreate)
{
    // Create a SharePoint list with the name that the user specifies.
    var hostUrl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
    var hostContext = new SP.AppContextSite(currentContext, hostUrl);
    var hostweb = hostContext.get_web();
    var listCreationInfo = new SP.ListCreationInformation();

    //title the list
    listCreationInfo.set_title(listToCreate);

    //set the base type of the list
    listCreationInfo.set_templateType(SP.ListTemplateType.events);

    var lists = hostweb.get_lists();
    //use the creation info to create the list
    var newList = lists.add(listCreationInfo);

    var fieldCollection = newList.get_fields();

    //add extra fields (columns) to the list & any other info needed.
    fieldCollection.addFieldAsXml('<Field Type="User" DisplayName="Requester" Name="Requester" />', true, SP.AddFieldOptions.AddToDefaultContentType);
    fieldCollection.addFieldAsXml('<Field Type="User" DisplayName="Manager" Name="Manager" />', true, SP.AddFieldOptions.AddToDefaultContentType);
    fieldCollection.addFieldAsXml('<Field Type="Boolean" DisplayName="Approved" Name="Approved" />', true, SP.AddFieldOptions.AddToDefaultContentType);

    //Attempting to enable moderation. This doesn't seem to have any effect.
    newList.set_enableModeration(true);

    currentContext.load(fieldCollection);
    currentContext.load(newList);
    currentContext.executeQueryAsync(onListCreationSuccess, onListCreationFail);     
}

function onListCreationSuccess() {
    alert("We've created a list since one didn't exist yet. Look in the site that hosts this app for the list." );
}

function onListCreationFail(sender, args) {
    //alert("We didn't create the list. Here's why: " + args.get_message());
}

Unfortunately it seems that .set_enableModeration(true); has no effect. I don't get any errors, but when I look at the settings for the list I created using this code I see this: enter image description here

So Content Approval clearly was not enabled via the method I'm using.

In order to set Content Approval using SP.List.enableModeration Property, the SP.List.update() Method have to be called as demonstrated below:

list.set_enableModeration(true);
list.update();
