I can think of two ways to do this.
You can add an accessor to CppObjects that gets called whenever a
value is assigned to 'onmousedown'. It creates a persistent handle to
the object and stores it in the c++ object. When there is a mousedown
event in c++ you can check if an event handler has been stored and
call it if there is one.
Alternatively you can store a reference to the javascript object
itself in the c++ object and look up the 'onmousedown' property
whenever an event occurs. If the property contains a function you
call it. This gives you a bit more overhead when there is an event
but may be simpler.
