Listen to the 'onEndEdit' event, detect if the checkbox is checked and do more actions according to your requirement.
$('#pg').propertygrid({
onEndEdit: function(index,row){
if (row.name == 'Address'){
var ed = $(this).propertygrid('getEditors',index)[0];
if ($(ed.target).is(':checked')){
//...
} else {
//...
}
}
}
})
