Error creating json cookie with jquery

Question

I’m trying to create a simple cookie with a json key value, but I’m getting it from the browser (click on the photo):

This is the plugin I’m using

Code, it goes below:

 $.cookie("gavetaMilagres", '{"sub_key_1":"sub_value_1", "sub_key_2":"sub_value_2"}'); 

I would like you to stay, for example, so:

"{\"time\": 1511524234\054 \"177.42.157.224\": 18881}"

But it’s like this:

%22%7B%5C%22sub_key_1%5C%22%3A%5C%22sub_value_1%5C%22%2C%20%5C%22sub_key_2%5C%22%3A%5C%22sub_value_2%5C%22%7D%22
