/*
For some reason, the change() event only fires when the input field loses focus.
Binding to other options ('change keypress paste focus textInput input') will 
fire the event several times, which is bad. The below code works even when 
content is pasted into the text field, and only fires once as expected.
*/
$('#search-form .term').bind('input', function(){
  console.log('this actually works');

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. 
To use the support version of these attributes, remove the android namespace.  

For instance, "android:colorControlNormal" becomes "colorControlNormal".  

These attributes will be propagated to their corresponding attributes within the android namespace 
for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.
