modal issue
Hi, i'm new to frameworks and i dont even know if i am at the right forum but i'll try here.

I'm creating a website for smartphones and choosed ratchet as framework.
But i came across a problem with the component "Modal".
When i link the button with the ID, it doesnt work right. 
When i click the button a blank page appears from the bottom, with a new header etc. but the header doesnt change, the old one stays, only the title disappears but the new one doesnt appear. why is that?!

plus, when i click on the button to open the modal it doesnt do anything.

i hope you guys can help 
thanks in advance, and sorry for my english, its not my native language
