Bootstrap Typeahead working on only two clicks in my scenario and Need to make work on dynamically for 20 rows

Below are code examples of my actual scenario. I need to call typeahead only when click on show button only once.jsfiddle https://jsfiddle.net/x6egfvwo/2 I have below table in html.

<table border="1" cellpadding="5" cellspacing="0" style="width: 100%">
            <tr>
                <td>City 1:</td>
                <td><input id="city1"></input>
                <button id="myButton1">Show</button>
                    <button id="clear1">Clear</button></td>
            </tr>

            <tr>
                <td>City 2:</td>
                <td><input id="city2"></input>
                <button id="myButton2">Show</button>
                    <button id="clear2">Clear</button></td>
            </tr>
        </table>

I am using bootstrap-typehead and below are my imports in header

<script src="https://code.jquery.com/jquery-1.11.3.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.1.0/js/bootstrap.min.js"></script>

<link rel="stylesheet"  href="https://maxcdn.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css" />

Below is my jquery function to display city list when click on show button and clear to destroy typeahead that previously initialized. This works only when i click on show button two times. I need to make this work in single click. Then i will be having nearly 20 rows. How to make this code dynamic that works for all the rows.

$('#myButton1').click(
                function() {

                    $('#city1').trigger('keyup');
                    $('#city1').focus();
                    $('#city1')
                            .typeahead(
                                    {
                                        source : [ 'Alabama', 'Alaska',
