JSOM - Scheduling a list item

Hello all

Currently working on a task that requires scheduling a list item using JSOM.

I did find that this can be done in server side code with the following code

using (SPSite site = new SPSite("http://serverName:1111/"))
        {
            using (SPWeb web = site.RootWeb)
            {
                SPList list=web.Lists["Doc Library"];
                SPListItem listItem = list.GetItemById(1);
                ScheduledItem scheduledItem = null;
                if (ScheduledItem.IsScheduledItem(listItem))
                {
                    scheduledItem = ScheduledItem.GetScheduledItem(listItem);
                }
                else
                {
                    throw new System.ArgumentException
                      ("SPListItem must support scheduling","listItem");
                }

                DateTime startDate = new DateTime(2011, 4, 6, 22, 50, 00);
                DateTime endDate = new DateTime(2011, 4, 6, 22, 51, 00);
                scheduledItem.StartDate = startDate;
                scheduledItem.EndDate = endDate;
                scheduledItem.ListItem.Update();
                scheduledItem.Schedule();
            }
        }

I would like to do the scheduling using JSOM in a button click.

I did a search for the js equivalent for this scheduled item and found this.

SP.Publishing.ScheduledItem

But am not sure how to use this.

Need your help on this.

Thanks in advance
