Find the location of ajax URL call on the server

Question

This is first time I heard about ajax. Right now I have a perfectly working script to plot data using armcharts. Source of this data seems to be ajax call and it goes like this.

$.ajax("myChannels/12").done( function(data) {
        createDeviceChart("chart", "Product Channels", ["Sensor1", "Senso2"], "Pulses", data);

I did grep -R "myChannels/12" / on the server where this script is located. My present output is "No such device or address".

I did this on the browser: "IP address/myChannels/12" and I see JSON data in the dictionary format. How and where to locate source of this data? and script?

(Newbie opinion) If you have access to the backend, where the service is deployed i.e. myChannels, it should be in the controllers assuming it is an MVC application.
