It doesn't look the arrow keys are detected, you have to implement it.

You should have somewhere in the function suggest a code that handle the arrow keys like:

...
switch(keyCode) {
    case 38: 
        //up arrow, highlight previous entry
        break;
    case 40: //down arrow 
        //up arrow, highlight next entry
        break;
    ...
}
