Cip was on the right path - you need to make the response JSON, and then properly access the JSON on the client side. Your ASMX method should look like this:

[WebMethod]
[ScriptMethod(ResponseFormat=ResponseFormat.Json)] // <--- To make it JSON
public string GetCompanyInfo(string id)     
{         
    Console.WriteLine("here2"+id);         
    return "aaa"; //never call "ToString()" on a string...
} 

And your client side JS success function should access the data like this (you need to access the d property for JSON generated by ASP.Net):

function OnSuccess(data, status) { 
     SetMainBody(data.d);  //"d" is the js object representation of the return 
                           //value from the web method. In your case it's just
                           //a string, but it could be a more complex object 
                           //or an array
}  

When you call the method via ajax, you should pass in the right arguments as well. Something like:

data: "{'id':'" + companyID + "'}",
