Task continue with not working upon exception

I am in a strange situation, I am using task and continue with upon faulted i am calling one method to process upon faulted or success but the function does not get fired.

Below is my code but upon expcetion it does not executes the UdpateResult method, what I am missing here.

 var task = new Task.Factory.StartNew(SomeMethod());

task.ContinueWith(
 t1 => Handler.UpdateResult(t1.Result, t1.Exception),
 TaskContinuationOptions.ExecuteSynchronously);

 try   
 {
         task.Wait();  
 }   
 catch (AggregateException exception)   
 {
   foreach (var innerException in exception.Flatten().InnerExceptions)
   {
      if (innerException is InvalidOperationException)
      {
            throw innerException;
      }

      throw new InvalidOperationException(string.Empty, innerException);
    }   
}
