How to prevent the popover div for hiding on clicking inside it for twitter bootstrap “dismissible popover”(data-trigger=“focus”)?

I have a a dismissible popover(data-trigger="focus") with a text box inside it. But as soon as I click inside the text box to type it dissappear because of the "data-trigger="focus". How do I make the div intelligently not disappear on click inside it? Here is my html :

  <head><script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js" ></script>
    <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script></head>
<body><div><a class="BookAppButton" href="" data-toggle="popover" data-html="true" data-placement="bottom" data-trigger="focus">Click Here</a></div></body>

Here is my jquery :

    $(document).ready(function(){
$('.BookAppButton').click(function(event){
    event.preventDefault();
    console.log("Button Clicked..");
});
$('.BookAppButton').popover({
        title : '',
        html : 'true',
    content:'<div style="border:black 2px solid"><p>Enter name : <input type="text"></input></p></div>'
    });
});

This is my jsfiddle link : http://jsfiddle.net/3g3o4xhw/

I am at my wits end.. please help.. Thanks in advance.

Clicks on the popover are hiding that popover because they are stealing the browser's focus. As soon as the button loses focus, the popover will be hidden (because we've set data-trigger="focus").

To address exact question you asked:

prevent the popover div for hiding on clicking inside it for twitter bootstrap “dismissible popover”(data-trigger=“focus”)?

The simplest way to fix this is to prevent clicks inside the popover from stealing focus by:

Adding an event listener to catch clicks inside the popover
Calling preventDefault() on the caught event

This will stop the focus from being stolen, and so stop the popover from being closed.

Note: We need to add the event listener on mousedown rather than click, because that is when the focus is set by the browser.

A more in-depth explanation of why we use mousedown and preventDefault() can be found on this StackOverflow answer: Prevent firing focus event when clicking on div

$(function() {
  $('[data-toggle="popover"]').popover()
})

$('body')
  .on('mousedown', '.popover', function(e) {
    console.log("clicked inside popover")
    e.preventDefault()
  });

<html>

<body>
  <script src="https://code.jquery.com/jquery.min.js"></script>
  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
  <a tabindex="0" class="btn btn-danger" data-toggle="popover" data-trigger="focus" title="Dismissible" data-content="Clicks in here won't steal focus">
    Dismissible popover
  </a>
</body>
</html>

You should use tigger: 'click'.

$('.BookAppButton').popover({
        title : '',
        html : 'true',
    trigger: 'click',
    content:'<div style="border:black 2px solid"><p>Enter name : <input type="text"></input></p></div>'
    });
});
