JQuery autocomplete displays all items, won't filter while typing

I am using JQuery UI autocomplete plugin on my web app. I was able to make it work, but the problem is, whenever I type in the textbox, all the items from my array are displayed. What I want to do is whatever I input in the textbox, I want to get all the matching items while typing.

this is my code

var products= [
              {"id":1,"value":"VITA.E D-ALPHA 400 UI X 30S","code":"00019","barcode":null,"case_cost":"168.00","pack_cost":"168.00","piece_cost":"5.60"},
              {"id":2,"value":"NATTOKIN 1000MG SOFTGELX6S","code":"0005","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},
              {"id":3,"value":"LIVERMARIN PLUS 1000MGX6S","code":"0006","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},
              {"id":4,"value":"LIVERMARIN PLUS X30S","code":"00063","barcode":null,"case_cost":"528.00","pack_cost":"528.00","piece_cost":"17.60"},
              {"id":5,"value":"NATTOKIN X 30S","code":"00065","barcode":null,"case_cost":"840.00","pack_cost":"840.00","piece_cost":"28.00"},
              {"id":6,"value":"OMEGAMAX 12X30S","code":"00067","barcode":null,"case_cost":"5472.00","pack_cost":"456.00","piece_cost":"15.20"}
             ];


$('#product_code').autocomplete({
    minLength:2,
    source : function(req,res){
        res($.map(products, function(item){
            return{
                id: item.id,
                value : item.code,
                label : item.value,
                description : item.value,
                case_cost : item.case_cost,
                piece_cost : item.piece_cost,
                pack_cost : item.pack_cost
            }
        }))
    },
    select : function(ev,ui){
        //some codes here
    },

}).focus(function() {
    $(this).autocomplete("search", $(this).val());
});

Follow jquery UI Autocomplete documentation

var products= [
              {"id":1,"value":"VITA.E D-ALPHA 400 UI X 30S","code":"00019","barcode":null,"case_cost":"168.00","pack_cost":"168.00","piece_cost":"5.60"},
              {"id":2,"value":"NATTOKIN 1000MG SOFTGELX6S","code":"0005","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},
              {"id":3,"value":"LIVERMARIN PLUS 1000MGX6S","code":"0006","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},
              {"id":4,"value":"LIVERMARIN PLUS X30S","code":"00063","barcode":null,"case_cost":"528.00","pack_cost":"528.00","piece_cost":"17.60"},
              {"id":5,"value":"NATTOKIN X 30S","code":"00065","barcode":null,"case_cost":"840.00","pack_cost":"840.00","piece_cost":"28.00"},
              {"id":6,"value":"OMEGAMAX 12X30S","code":"00067","barcode":null,"case_cost":"5472.00","pack_cost":"456.00","piece_cost":"15.20"}
             ];

For example you can use static source and let jquery handle matching:

$('#product_code').autocomplete({
    minLength:2,
    source :$.map(products, function(item){
            return{
                value : item.code,
                label : item.value
            }
        }),
    select : function(ev,ui){
        //some codes here
    },

}).focus(function() {
    $(this).autocomplete("search", $(this).val());
});

Or you can use more flexible callable as source:

$('#product_code').autocomplete({
    minLength:2,
    source : function(req,res){
          var search = req.term.toLowerCase();
          res(products.reduce(function(matches, product){
             if ( -1 !== product.code.toLowerCase().indexOf(search) )
                matches.push({value:product.code,label:product.value});
             return matches;
         }, []));
    },
    select : function(ev,ui){
        //some codes here
    },

}).focus(function() {
    $(this).autocomplete("search", $(this).val());
});

Filter the array within source callback where use Array#filter method for filtering and String#includes for checking string contains the search term.

var products= [              {"id":1,"value":"VITA.E D-ALPHA 400 UI X 30S","code":"00019","barcode":null,"case_cost":"168.00","pack_cost":"168.00","piece_cost":"5.60"},              {"id":2,"value":"NATTOKIN 1000MG SOFTGELX6S","code":"0005","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},              {"id":3,"value":"LIVERMARIN PLUS 1000MGX6S","code":"0006","barcode":null,"case_cost":"0.00","pack_cost":"0.00","piece_cost":"0.00"},              {"id":4,"value":"LIVERMARIN PLUS X30S","code":"00063","barcode":null,"case_cost":"528.00","pack_cost":"528.00","piece_cost":"17.60"},              {"id":5,"value":"NATTOKIN X 30S","code":"00065","barcode":null,"case_cost":"840.00","pack_cost":"840.00","piece_cost":"28.00"},              {"id":6,"value":"OMEGAMAX 12X30S","code":"00067","barcode":null,"case_cost":"5472.00","pack_cost":"456.00","piece_cost":"15.20"}             ];
