Please help me with this scope issue

I couldn't figure this one out. Maybe you can?

I have a dialog.UIElement of type 'html'. I use it with Ajax calls to update a div container (innerHTML). The innerHTML gets updated with tags containing 'onclick' events that needs access to the functions within the dialog plugin.

In short: How can I call the fMyFunction() within the 'html' element using the code below?

CKEDITOR.dialog.add( 'myPlugin', function( editor )
{
   var fMyFunction= function(someVariable){
       console.log(someVariable);
   };

   return {
      title : 'My Plugin',
      minWidth : 300,
      minHeight : 60,
      onOk : function()
      {
        ...
      },
      onShow : function()
      {
      ...
      },
      contents :
         [{
            id : 'general',
            elements :
            [
               {
                   type:'html',
                   html:'<div onclick="fMyFunction('what is the scope?');"></div>'
               }
            ]
         }]
   };
} );
