swfobject js axshockwave(external interface) call function

I have a,

                axShockwaveFlash1.FlashVars = "width=" + "380" + "&height=" + "500" + "";
                axShockwaveFlash1.LoadMovie(0, Application.StartupPath + "\\Sample.swf");
                axShockwaveFlash1.Height = int.Parse("380");
                axShockwaveFlash1.Width = int.Parse("500");
                axShockwaveFlash1.Play();

and a function as,

           axShockwaveFlash1.CallFunction("<invoke name=\"getDetails\" returntype=\"xml\"><arguments><string>" + "PowerPointPresentation" + "</string><string></string><string>" + null + "</string></arguments></invoke>");

How to implement it in javascript,

I tried swfobject.js,

       swfobject.embedSWF("/Swf/Sample.swf", "presentationembed", presentationwidth.value, presentationheight.value, "9.0.0", flashvars, params, attributes, function (e) { "<invoke name=\"getDetails\" returntype=\"xml\"><arguments><string>"PowerPointPresentation" </string></arguments></invoke>" });

but It didn't work out,

I want to know how to implement, "axShockwaveFlash1.CallFunction("<invoke name=\"getDetails\" returntype=\"xml\"><arguments><string>" + "PowerPointPresentation" + "</string><string></string><string>" + null + "</string></arguments></invoke>");" in javascript, that is using swfobject js?

I looked into this docs and I didn't get anything, https://code.google.com/p/swfobject/wiki/api
