How come my custom keyboard layout won't work in Pages?

Greetings.

I have created a custom keyboard layout through the program Ukelele. When I had saved it and selected it as the current keyboard layout, I begin to type and it types as if the keyboard layout were the default US. I changed the font thinking some of the characters must not show up in some of the fonts, nothing; still typing in a default US format. I then went to TextEdit and it worked perfectly fine. It acknowledged the custom keyboard layout I was using. :

My question(s) is(are): How come in TextEdit my custom keyboard layout can work, but in Pages it doesn't? Is there something I need to change for Pages to start using my custom keyboard layout?
