Application Is Not Using Called Custom Font

I’ve downloaded the TrueType Arial Black font. The icon name is “ARIBLK” and the font name is “Arial Black”, and the font is on my application’s folder.

On simulator, we can use the “Arial Black” font because it already exists on the Corona SDK folder or I guess it’s so. But calling it on device, the font does not turn the text to bold. I downloaded the font trying to make it work on device and turn my texts to bold, but it isn’t working. The code I’m using is the following:

local text = display.newText("Blablabla...", 0, 0, "Arial Black", 20);  

Any ideas on how to make it work?
