Proper format for ng-repeat Checkboxes?

I want to create a form that collects a persons email address and then a dynamic list of check boxes. (The dynamic part will come from a DB query, but for purposes of this question, I am providing a sample scope array.

What I need help with is how to set up the ng-repeat to allow for that dynamic list to be made available as a set of post vals upon submit.  The following is a modified piece of the code for demo purposes.

Here is the key portion of my Angular Code:

$scope.seminars = [
    { id: 1, name: 'Seminar One' },
    { id: 2, name: 'Seminar Two' },
    { id: 3, name: 'Seminar Three' },
    { id: 4, name: 'Seminar Four' }
  ];

$scope.submitFm = function (data) {
	console.log("Arrival at submit for checkboxes");
	console.log(data);
};

And here is the HTML Code. I am creating a form that the attendee fills out to select which seminars they want to attend.  The first field of the form is email. The second field is a check field that I've created.  The third is my attempt at an ng-repeat to get the list of selected seminars.

<form id="attnFm" name="attnFm" class="form" ng-if="!msg">
       <input type="hidden" ng-model="attn.post_actions" ng-init="attn.post_actions='matm_attend'"/>
       <div class="row">
		 <label class="sr-only" for="email">email</label>
		 <input type="email" class="form-control" id="email"
                                         placeholder=" Email" 
                                         ng-model="attn.email"/>
       </div>
						
	<div class="row">
		<label class="sr-only" for="checky">checky</label>Check Box
		<input type="checkbox" class="form-control" id="checky"
                                         ng-model="attn.checky"/>
         </div>
	<div class="row">
            <div ng-repeat="seminar in seminars"> 
		<label class="sr-only" for="seminar.name">seminar.name</label>
		<input type="checkbox" class="form-control" id="seminar.id" ng-model="seminar.id"/>
          </div>
         <div class="row">
                                	<button type="submit" id="frmsbmt" class="btn btn-primary btn-xl"
                                           ng-disabled="attnFm.$invalid" ng-click="submitFm(attn)">
                                                  View <i class="fa fa-send"></i>
                                    </button>
          </div>
 </form>

The main problem I am having is what to use as the model for my ng-repeat seminar field. If I try ng-model="attn.{{seminar.ID}}" I get an error. When I set it to ng-model="attn.seminar.ID" then all three of the ng-repeat fields are linked and when I click one, all show.  

So what do I set the ng-model= field to get it to work?

When I hit submit and view the console with the developer tools.  Here is what shows on the developer console view:

checky: true
email: "myemail@aol.com"
​post_actions: "matm_attend"
​seminarID: true

So how do I get the checkboxes of ng-repeat to properly show up in my console view log?
