Contextmenu with checkbox

Hi,
How to fire onclick on the contextmenu?. If I use checkbox, the ‘onClick’ works only when I clicked the checkbox. But when I select the item, nothing happens.

You need to attach theonItemClick event to the contextmenu:

on:{ 
    onBeforeShow: function(){ ... },
    onItemClick:function( id, event, node ){ ... }
}
