Ajax autocomplete jquery is not working when text field is not empty

I'm working with Ajax autocomplete for jquery and my HTML code is

<input type="text" name="autocomplete" id="globalBCCAutoComplete">

and my autocomplete JS code is

$(document).ready(function() {
    var countries = [
        { value: '{contract_name}', data: 'Contact Name'},
        { value: '{user_company}', data: 'User Company' }
    ];
    $('#globalBCCAutoComplete').autocomplete({
        lookup: countries,
        onSelect: function (suggestion) {
            //alert('You selected: ' + suggestion.value + ', ' + suggestion.data);
            console.log('You selected: ' + suggestion.value + ', ' + suggestion.data);
        }
    });
});

and it is working fine, but when I add value attribute in text field:

<input type="text" name="autocomplete" id="globalBCCAutoComplete" value="This is test">

After added value autocomplete is not working. What is the problem?

from the comments I understand all you want is to append the initial value set on the input to the suggestions object so it will act as a prefix.

why did not you say so ?

using your code:

HTML:

<input type="text" name="autocomplete" id="globalBCCAutoComplete" value="john">

JAVASCRIPT:

$(document).ready(function() {

        let countries = [
           { value: '{contract_name}', data: 'Contact Name'},
           { value: '{user_company}', data: 'User Company' }
        ];

        //get current value from the textbox
        let initialTextValue = $('#globalBCCAutoComplete').val().trim();

        //append the value to your JSON objects.
        $(countries).each(function(key, country) {
            country.value = initialTextValue + ' ' + country.value
        });

        //the rest of your code:
        $('#globalBCCAutoComplete').autocomplete({
            lookup: countries,
            onSelect: function (suggestion) {
                console.log('You selected: ' + suggestion.value + ', ' + suggestion.data);
            }
        });
    });

jsfiddle example: https://jsfiddle.net/7g4nnnoz/5/

an alternative would be ES6 arrow function with the .map() function:

//append the values to the json object.
countries.map( (country) => {
    country.value = initialTextValue + ' ' + country.value
});
