Android : element not hidden in a keyup event on mobile

I have a keyup event which gets the value from an input and checks it against a list of items. The items that do not match, will be hidden.

$(".search-cust").on('keyup',function(e) {
  e.preventDefault();
  var value = $(this).val().toLowerCase();

  if( value.length == 0 ) {
    $('#station-list li').each(function() {
      $(this).show();
    });
    return false;
  }

  $('#station-list li').each(function() {
    var name = $(this).find('.name').text().toLowerCase();
    var comp = $(this).find('.company').text().toLowerCase();
    var mobi = $(this).find('.mobile').text().toLowerCase();
    var cust = $(this).find('.customernumber').text().toLowerCase();

    if(name.match( value )) {
      $(this).show();
    } else if(mobi.match( value )) {
      $(this).show();
    } else if(cust.match( value )) {
      $(this).show();
    } else if(comp.match(value)) {
      $(this).show();
    } else {
      $(this).hide();
    }
  });
});

This works perfectly on desktop but on mobile (in my testcase Samsung Galaxy S2), the element is not being hidden. The event itself works and I did some alerts and saw that it reaches the else statement but is not hiding the element.
