not able to paste content in visual format editor

Amrita1

After retrieving content, I want to copy it in a visual format editor.

Everything is working fine except this:

top._dcWin.eWebEditPro.instances[0].asyncCallMethod("pasteHTML", [tagVal], null, new Function());

the function is:
function handle_selection_cat(catalog_selection)
{
var tagVal = "{CATALOG:"+catalog_selection+"}";
alert(tagVal);

top._dcWin.eWebEditPro.instances[0].asyncCallMethod("pasteHTML", [tagVal], null, new Function());
window.close();
}


I am getting the required alert...Is there any supporting file I am missing...?

Thanks in advance.
