Issue working UI5 with JSON

Hi I am new to UI5 and JSON script.

I am trying to develop UI5 with JSON and backend with ABAP code.

Step1. In ABAP: I created RFC function module to select 4 fields from data base and  tested this function module working fine.

and I created webservice on this RFC function module.

Step2: In html: I  wrote small html code, please find the attachment.

Ste3: executed this html cpde...I can see the table with 4 columns on my IE9 browser but did not able to see the data in the table,,,i,e where ever I am calling URL in my html page, that is not working due to that function module is not triggered...

Can you please help me on this how to fix ...and how to map the JSON code with sap webservice data.

Thanks for advance.

Regards,

Naresh.
