Get element inside ng-transclude

I created a directive and I'm trying to get a DOM element inside ng-transclude, but when I do a find () looking for elemnto, jqLite does not find

HTML using directive:

<categorias>
 <span class="category-name"> categoria </span>
</categorias>

Template of the directive:

<div id="categorias">
  <ng-transclude></ng-transclude>
</div> 

Javascript da directive:

function categorias() {
    var directive = {
        restrict: 'E',
        replace: true,
        templateUrl: 'categoria.html',
        transclude: true,
        link: function(scope, elem, attrs) {
            elem.on('mouseover', function() {
                var name = elem.find('.category-name'):
                console.log(name)
            })
        }
    }

    return directive;
}

When you mouseover the element in the console.log, an empty object appears:

JQLite {}

How do I get the dom elements that are inside ng-transclude?
