How to implement EditorAttribute functionality when overriding ICustomTypeDescriptor

I am trying to implement ICustomTypeDescriptor. I have implemented most of the attributes but I am having problems with EditorAttribute type. Looks like is not recognizing some of my editors, specially the ones I have derived. Since multiline editor and one of the UITypeEditors is working.

I have tested the same class loading it in a property grid and they work just fine, but when I load the same properties in my own implementation some of the EditorAttribute appear to be broken (like showing as simple test) instead of showing the button to select a file for example. Here is my code:

foreach(var property in type.GetProperties()) {
  ...
  foreach(CustomAttributeData attribData in property.GetCustomAttributesData()) {
      ...
      if(attribData.AttributeType == typeof(EditorAttribute)) {
        EditorAttribute editorAttr = (EditorAttribute) property.GetCustomAttributes(typeof(EditorAttribute), true).GetValue(0);
        converterType = Type.GetType(editorAttr.EditorTypeName); // converterType, 

        TypeDescriptor.AddAttributes(converterType, new EditorAttribute(editorAttr.EditorTypeName, editorAttr.EditorBaseTypeName));
      }
    }
    ...
}
