ok, how this parameter get updated? You receive it on every request? If so,
the usual way of to build your render logic dynamically is to implement
component onBeforeRender method, rather than on your component constructor.
See the ListView code for example: based on the model object (an list) the
list items are dynamically add to component. And that render logic is tested
based on list every component render. Similarly, you can have your render
logic executed based on a parameter every component render...
