navigator.geolocation.getCurrentPosition sometimes works sometimes doesn't

So I have a pretty simple bit of JS using the navigator.geolocation.getCurrentPosition jammy.

$(document).ready(function(){
  $("#business-locate, #people-locate").click(function() {
    navigator.geolocation.getCurrentPosition(foundLocation, noLocation);
  });

  navigator.geolocation.getCurrentPosition(foundLocation, noLocation);

  function foundLocation(position) {
    var lat = position.coords.latitude;
    var lon = position.coords.longitude;
    var userLocation = lat + ', ' + lon;
    $("#business-current-location, #people-current-location").remove();
    $("#Near-Me")
      .watermark("Current Location")
      .after("<input type='hidden' name='business-current-location' id='business-current-location' value='"+userLocation+"' />");
    $("#people-Near-Me")
      .watermark("Current Location")
      .after("<input type='hidden' name='people-current-location' id='people-current-location' value='"+userLocation+"' />");
  }
  function noLocation() {
    $("#Near-Me").watermark("Could not find location");
    $("#people-Near-Me").watermark("Could not find location");
  }
})//end DocReady

Basically what's happening here is we get the current position, if it's obtained, two "watermarks" are placed in two fields that say "Current Position" and two hidden fields are created with the lat-long data as their value (they're removed in the beginning so they don't get duplicated every time). There are also two buttons that have a click function tied to them that do the same thing. Unfortunately, every third time or so, it works. What's the problem here???
