Getting an error when using jsonRpcService on Xpages - xpages

Question

I'm trying to use jsonRpcService to print a value on console. Just for testing.
But when i call the method i recieve this error on browser console:
POST http://localhost/Teste.nsf/Teste.xsp/RpcService?$$viewid=!ei0pdt23xx! 400 (Bad Request)
Error: Unable to load /Teste.nsf/Teste.xsp/RpcService?$$viewid=!ei0pdt23xx! status:400(…)
Unable to load /Teste.nsf/Teste.xsp/RpcService?$$viewid=!ei0pdt23xx! status:400
Error: Unable to load /Teste.nsf/Teste.xsp/RpcService?$$viewid=!ei0pdt23xx! status:400(…)
Error: Unable to load /Teste.nsf/Teste.xsp/RpcService?$$viewid=!ei0pdt23xx! status:400(…)
Here is the image of the error:

I already searched a lot for one solution to this error but i got nothing.
This is the code that i'm using:
<xe:jsonRpcService id="jsonRpcService1" serviceName="metodos"
pathInfo="RpcService">
<xe:this.methods>
<xe:remoteMethod name="teste" script="print('teste')"></xe:remoteMethod>
</xe:this.methods>
</xe:jsonRpcService>
And this is the code that i'm using on console to call the function
metodos.teste()
Does anyone knows what i'm doing wrong?
Thanks

You have to return a value in your script and your client has to wait for answer with a callback function.
This is a working example:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view
xmlns:xp="http://www.ibm.com/xsp/core"
xmlns:xe="http://www.ibm.com/xsp/coreex">
<xe:jsonRpcService
id="jsonRpcService1"
serviceName="metodos"
pathInfo="RpcService">
<xe:this.methods>
<xe:remoteMethod
name="teste"
script="return 'teste'">
</xe:remoteMethod>
</xe:this.methods>
</xe:jsonRpcService>
<xp:button
value="Test"
id="button1">
<xp:eventHandler
event="onclick"
submit="false">
<xp:this.script><![CDATA[
var deferred = metodos.teste();
deferred.addCallback(function(result) {
alert(result);
});]]></xp:this.script>
</xp:eventHandler>
</xp:button>
</xp:view>
When you click on button "Test" an alert box shows up with the message "teste".
You can add additional code before return 'teste' like your original print('teste'). The script just has to return something...
