File upload in UI5 works only for the first time

Hello,

I am using  sap.ui.unified.FileUploader to upload an excel file into my UI5 application. I have written the function to read the file data in 'change' event. However 'change' is triggered only for the first time we upload a file. When we change the content of the file and save it, then re-upload the same file, 'change' event is not triggered again.

If I change the file name or log out of the application and come back then the upload works fine as the 'change' event is fired again.

Any help is appreciated!!

Thanks,

Charles
