JS - Refresh Advise

I have a question in terms of User Experience, i have the JS:

$(document).on( "click", "input:radio,input:checkbox", function() {
        getContent($(this).parent(),0);
    });

The above JS gets the contents from radios and checkboxes, and it refreshes the page to show dependencies. For eg if I check on yes, and the dependency is on yes, show text box, the above works!

What I want to know is, if there is a better way to do the same thing, but in a more friendly was, as this is at times, making the pages slow. Especially if I do alot of ticks/checks in one go, I miss a few, as the parent refreshes!

Help!
