I am unable to open a "browse file" button using javascript code, while "submit"
button works properly.

In the example page, I just code the "browse file" button. It's very simple
code; you click on the link "I will try to open the browse button" and that
executes a javascript function that get the button object using
"document.getElementById()" and calls the "click()" method of the button.
Nothing happens.

This example works if the button is a "submit" button as you can see if you
click on the other link "I will try to click the submit button".

The reference talks about that method:

Steps to Reproduce:
1. Load de expample URL
2. Click on the link "I will try to open the browse button"

Actual Results:  
Nothing happens

Expected Results:  
open a browse file dialog window
