'Invalid character error on character backtick in IE (tried to fix but doesn't work)

I'm having a font problem backtick in IE; I get the error invalid character.

The line where I get the error is:

document.querySelector('form').action = `create.html?id=${id_u}`;

I try to change the line to try to solve the problem but it doesn't work for me.

document.querySelector('form').action = "create.html?id="+id_u;

Where did I go wrong? Can anyone kindly help me?
