Pass multiple params to iso-method

[that1guy]

 $scope.$emit('iso-method', {name:'layout', params:instance.elements[0], function(){
                console.log("done");
            }});

gives me error:

Uncaught SyntaxError: Unexpected token ( search.js:30

If I just don't pass in a callback function I get error:

That initial code has a typo, just fyi.

{
  name: 'layout',  
  params: instance.elements[0], 
  function(){} // this function has no paramater, so it will break the object
}

{
  name: 'layout',  
  params: instance.elements[0], 
  function: function(){} // this would be a proper object
  // using the word function as an attribute is bad form in JS last I checked
}
