Show checkboxes checked after data bindnig in angularjs

Hi,
I want to show checkboxes in a dropdown html control. I am binding data using angularjs.
This type of control is not available in html. So I have created a div and applied styling to it to look like a dropdown.
Using ng-repeat, I am able to create checkboxes inside it.
When a user checks a checkbox, its text is stored in database on button click.

What I want it, when page loads, the respective checkboxes should get checked whose values we stored in database.

Here is the HTML:

HTML

<dl class="dropdown"> 
  <dt>
      <a href="#">
	<span class="hida">Select</span>    
	<p class="multiSel"></p>  
      </a>
  </dt>
  <dd>
      <div class="mutliSelect">
	<ul>
	   <li class="floatLeft widthFull" data-ng-repeat="code in MultipleRhythm">
		<label class="floatLeft"> <input type="checkbox" class="floatLeft multiCheckbox" value="{{code.Name}}" />{{code.Name}}</label> 
	   </li>
        </ul>
      </div>
   </dd>	
</dl>

Here is js:

JavaScript

$scope.MultipleRhythm = $scope.ManagerCollection["Multiple Rhythm"]["Multiple Rhythm"];

This gives me a collection to loop through using ng-repeat

JavaScript

$scope.SelectedMultipleRhythm = $filter('GetMultiSelectedOptions')($scope.MultipleRhythm, $scope.ManagerCollection["SelectedMultipleRhythm"]);

This gives values selected by user which come from db. This is comma separated.

If user has selected 3 values, I want to show those three checkboxes checked.

What I have tried:

I tried using ng-if, ng checked that if the code.Name == SelectedMultipleRhythm, then show checkbox checked. But no luck.
