Webix JS

I want to handle an event on button in a toolbar.
whenever, we click on a button it has to go to other jsp or html file.
how can we do this one?

You can use same code as for standalone buttons

$$("buttonID").attachEvent("onitemclick", function(){
       webix.send("/some/servlet", null, "GET");
});
