Could not able to render current date in textbox using jquery datetime picket.

I have input text box for date. I am using JQuery Date picker. 
I want to set and render the current date in my text box when page loads as default.

I could not able to do it. This is my code.  Its not working. 

Please look at and help me out.

What I have tried:

<pre><label for="dateSelection">Date:</label>
<span style="background-color: antiquewhite; padding-top: 3.6px; padding-bottom: 3.6px;">
<input type="text" id="dtID" name="dateSelection" placeholder="mm/dd/yyyy" ng-model="txtDate" required />
<span class="glyphicon glyphicon-calendar" style="padding-right: 3.6px;"></span>
</span>

   
    $(document).ready(function () {
        $('#dtID').datepicker({
            changeMonth: true,
            changeYear: true,
            showAnim: 'slideDown',
            duration: 'fast',
            dateFormat: 'mm/dd/yy',
            onSelect: function (date) {
                $scope.txtDate = date;
                $scope.$apply();
            }
        }).setDate(new Date());
    });
