Bootstrap3 remote content using PHP

Again breaking my head in Bootstrap 3. I have been using BT3 with a modal window. The below code works and fetch the remote modal window for the first time and doesn't work in my second click.

I have checked the below forums:

Bootstrap 3 with remote Modal

From the documentation:

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a> 

index.php

 <a data-toggle="modal" data-target="#myModal" class="btn btn-primary" data-keyboard="false" data-backdrop="false" href="emp_details.php?id=1">Employee 1</a> <a data-toggle="modal" data-target="#myModal" class="btn btn-primary" data-keyboard="false" data-backdrop="false" href="emp_details.php?id=2">Employee 2</a> <a data-toggle="modal" data-target="#myModal" class="btn btn-primary" data-keyboard="false" data-backdrop="false" href="emp_details.php?id=3">Employee 3</a> <div class="modal fade" id="myModal"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">X</button> <h4 class="modal-title">Test</h4> </div> <div class="modal-body">Test</div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> 

emp_details.php

 <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">X</button> <h3 id="myModalLabel">Modal header</h3> </div> <div class="modal-body"> <?php print_r($_GET); ?> </div> <div class="modal-footer"> <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button> </div> 

So now my questions are:

1. Is there a way to get the modal box dynamically each time when the href is clicked?
2. Is there anyway to load the remote content dynamically without any issues?
