Bootstrap typeahead not Working inside the Bootstrap Modal

I am using codeigniter framework and i am using bootstrap typeahead and all is fine but my problem is when i put it inside the bootstrap modal the bootstrap typeahead will not work. can someone help me? please. this is my code ``` <a data-target="ajaxify" data-toggle="modal" href="<?php echo base_url()?>task/add_task" class="no-u quick-task"> <h4>Task</h4> <span>This is a simple description</span> </a> ``` and inside my add_task controller i call the view task_view.php and task.js but it seems that the typeahead is not working inside the bootstrap modal. this is the content of task.js ``` $(document).ready(function(){ $("#assign_to").typeahead({ source: [{value: 'Charlie'}, {value: 'Gudbergur'}] }); }); ``` this is the content of task_view.php : just a sample. ``` <div id="ajaxx" class="modal hide fade"> <div class="modal-header"> <a class="close" data-dismiss="modal">&times;</a> <!--Your title here --> <h3>Modal Heading</h3> </div> <div class="modal-body"> <form><input type="text" name="assign_to" id="assign_to" /></form> </div> <div class="modal-footer"> <!--Your dont change the attributes only the value here --> <a href="#" id="n0" class="btn n0" data-dismiss="modal">Close</a> <a href="#" id="y1" class="btn btn-primary y1" data-submit="modal">Save</a> </div> ```
