Magento2 Admin Product Edit Form file upload - Showing error $_FIles array is empty

[maratheprash]

Hey there,
I am working on document upload functionality I have done it already from Frontend. Same functionality I am doing with Magento admin section on Product Edit Form. 
I have added my custom tab on the form and also added the code with "Add More " functionality. 

I get all the input in my "ProductSaveAfterObserver" except uploaded files. It seems like it may be because of enctype="multipart/formdata" but I don't know how to handle this on backend  (or magento already handled those things) . 

When I try to print $_FILES - I get ouput "$_FILES is empty";

Can anyone help me to resolve this ?
