Progress bar in Ruby/Green Shoes

Question

I am trying to get a progress bar to work in Ruby with Green Shoes. My problem is that the progress of the bar that I am creating isn't showing. The state of my bar is either empty at the begining and during the execution of the code or full at the end.

Here is the structure of my code:

Shoes.app do
  button("Run") do
    progress_bar = progress left: 10, top: 10, width: 235
    backup_exe = File.open(File.dirname(__FILE__) + "/backuplist.txt","r+")
    count = 0
    File.open(backup_exe) {|f| count = f.read.count("\n")}
    counter = 0
    count = count.to_f
    puts count
    animate do |counter|                
    backup_exe.each  do |line|
        counter=counter+1
        progress_bar.fraction = ((counter/count)*10).round / 10.0
        puts progress_bar.fraction
            sleep(2)
        end
    end
  end
end

Thank you in advance for your help!

Resolved! I need to put values that populates fraction in a new Thread. Thanks mudasobwa for your input!
