Multiple calls to action method for statuschanged event of IQueueBuild

Hi All

I am trying to automate the build deployment process using TFS in MVC.
While getting the status of build after build is triggered, I am getting redirected to action method after the initial statuschanged event.This issue is occuring after deployment. Application is working fine on local.
Please find below the code snippet

Build.statuschanged += new StatusChangedEventHandler(queueBuild_statuschanged)

Here statuschanged event will continuously get the status of the build whenever the status changes from Inprogress to Queue/ Completed.
So Sometimes I am getting status as completed but many times after first status change, the execution control is nevigating to controller method.

Please let me know how to avoid this multiple call to actionmethod as this is causing session value to be set to Null and nothing is working ahead.

Thanks in Advance
