Using jquery .css method to style divs not working

Hi Guys,

I’m pretty new to the whole cordova / ionic scene, at the moment I’m working on a simple app in which I need to use a jquery css method to determine the padding above a div to position it in the center of the view. I have used this kind of function before in standard web development, however it doesn’t seem to work here. I have imported jquery in the index.html, above the js and css files. I am using jquery ver 1.11.1.

Here is my code

$('#textbox').css({"padding-top":(((window.innerHeight-100)/2)+'px')});

The console doesn’t show any errors, which makes me think it’s working however the text div is still sitting at the top of the page.
