call js function from root_url javascript

[r1si]

hi guys,
I use node js plugin , and I write this code:

function test_me(){
console.log("work");
}

webview(function(err, api) {
var win = api.window({ root_url: 'file:///Users/USER/Documents/LOCAL/SVILUPPO_WEB/test.html' });
win.show();
win.maximize();
win.on("closed",function(){
process.kill();
});
});

and in my local pc inside test.html

<script type="text/javascript"> jQuery(document).ready(function() { parent.test_me(); }); </script>

I'm trying to invocate remote function with parent.function() but don't work ...
how can I do?
