This link provides a way to create a new publishing page using ECMA SCRIPT . But it creates a page with a random name .

I want to set its Name and Pagelayout at the creation of page.

pageInfo = new SP.Publishing.PublishingPageInformation();

pageInfo.set_name($("MyHomePage.aspx");
pageInfo.set_pageLayoutListItem("CT_CustomLayout");

newPage = pubWeb.addPublishingPage(pageInfo);
