Checkbox on touchscreen | Using icheck library

I am building a kiosk application and using the icheck libray to style checkboxes.

I am coding the checkbox this way:

<input type="checkbox" name="test" id="test1" value="10">

It works perfectly fine when I use the application on a normal browser with a mouse, however when I test it on the kiosk with a touch screen, for the checkbox to tick and untick itself, it is not working correctly.

If you click directly on it, it doesn't work, however slightly lower or on the right it does.

Any ideas ?
