Error while Calling Custom method using Ajax

Question

We have created GetValue() method in dll SalesForceCommunityQ for fetching data from Database and render it in tabular form in the administrator plugin editor.

[WebMethod]
public static string GetValue()
{
    Some code here to get data from database
}

This method is called using Ajax in same dll in the below source code.

SourceCode:

public string GetConfigurationHtml(string apiJson)
{
    return string.Format(@"
<script type='text/javascript'>
            jQuery(document).ready(function(){{
                        GetData();
            }});
            function GetData(){{
                    jQuery.telligent.evolution.get({{
                        url:'SalesForceCommunityQ/GetValue', 
                        data: {{}},
                        contentType: 'application/json; charset = utf-8',
                        dataType: 'json',
                        success: function(_data) {{
                            console.log(_data);
                        }}
                    }});
            }}
 </script>
    ", apiJson);
}

However we are getting below error.

ERROR: Failed to load resource: the server responded with a status of 404()/SalesForceCommunityQ/GetValue:1 )

What is the url value we need to use here?
We reffered the link( community.telligent.com/.../exposing-configuration-options)

Updated code

Hi Mahesh Mundra . WebMethod attributes will not work here. However, there are a number of ways to implement custom Ajax callbacks for your UI, including directly inside your widget using executed file urls that potentially call custom scripted extension methods, or even custom plugins that define your own REST endpoints or raw HTTP handlers. 
 I'd recommend starting with the following for the basics of how widgets and plugins work together, along with how to perform Ajax requests against widget-defined files and using plugin-defined APIs to access and serve your data to your widget:
