Answer 2

I don't know exactly how you're WCF service is currently configured, but the following code block will call the service and the results would be passed into the callback.

$.ajax({
    cache: false,
    type: "GET",
    async: false,
    url: "http://xx.x.x.xxx/GAdmin/WGService/Service1.svc/RetrieveData?term=apple",
    contentType: "application/json",
    success: function (response) {
        /* SUCCESS FUNCTION */
    },
    error: function (error) {
        /* ERROR FUNCTION */
    }
});
