Concatenate custom data attributes inside attr() - error in IE 11: SCRIPT1028

Question

Anyone can help me?

I'm setting several custom data attributes (for skrollr), everything works fine, but in IE appears this error in the third line: SCRIPT1028: Expected identifier, string or number

There is another way to concatenate the string and the variable ["data-" + h_window] inside a attr()

  $(".line").attr({
    "data-0":  "height:70px; visibility:visible;",
    ["data-" + h_window]: "height:0px; visibility:hidden;"
  });

This error happens for every line similar to the third. block of code Thanks!
