Continuous Web Job with timer trigger and Blob trigger

Question

I have the following functions in the same web job console app that uses the azure jobs sdk and its extensions. The timed trigger queries an API end point for a file, does some additional work on it and then saves the file to the blob named blahinput. Now the second method "ProcessBlobMessage" is supposed to identify the new blob file in the blahinput and do something with it.

public static void  ProcessBlobMessage([BlobTrigger("blahinput/{name}")] TextReader input,
        string name, [Blob("foooutput/{name}")] out string output)
    {//do something        }

    public static void QueryAnAPIEndPointToGetFile([TimerTrigger("* */1 * * * *")] TimerInfo timerInfo) { // download a file and save it to blob named blah input}

The problem here is : When I deploy the above said web job as continuous, only the timer triggered events seems to get triggered while the function that is supposed to identify the new file never gets triggered. Is it not possible to have two such triggers in the same web job?

From this article: How to use Azure blob storage with the WebJobs SDK

The WebJobs SDK scans log files to watch for new or changed blobs. This process is not real-time; a function might not get triggered until several minutes or longer after the blob is created. In addition, storage logs are created on a "best efforts" basis; there is no guarantee that all events will be captured. Under some conditions, logs might be missed. If the speed and reliability limitations of blob triggers are not acceptable for your application, the recommended method is to create a queue message when you create the blob, and use the QueueTrigger attribute instead of the BlobTrigger attribute on the function that processes the blob.
