Error with binding an attribute value - angular include and directives

I am trying to include some directives dynamically according some data I receive from my server. I have asked this so before and now the directive is uploaded, but there is some error I see in the console, here is what I get: Syntax Error: Token 'type' is unexpected, expecting [:] at column 3 of the expression [{{type}}] starting at [type}}].

Here is the main page html:

<div ng-repeat="type in bet.bet_types">
    <div ng-include src="getBetTypeById(type.id)"></div>
</div>

Here is the getBetTypeById(id) function from the scope:

    $scope.getBetTypeById = function(id)
    {
        switch(id)
        {
            case 1:
                return '/views/partials/1.html';
                break;  
...

Here is the 1.html:

<test-test bettype={{type}}></test-test>

here is the tets-test directive:

var app = angular.module('soccerWinner', []);

app.directive('testTest', function()
{
    return {
        restrict: 'E',
        replace: true,
        scope:
        {
            bettype: '='
        },
        templateUrl: '/views/partials/directives/bettaype_soccer_winner.html',
        controller: function()
        {
            alert('dfd');
        }
    };
});

And here is the bettaype_soccer_winner.html:

<h2>test</h2>

There is no alert after the directives are loaded, and the above error is seen in the console.

What is wrong with what I do? I believe that the issue is related to the line of code <test-test bettype={{type}}></test-test>

Here is a sample of an type:

{"id":1,"name":"Winning Team or Tie","description":"Choose the winnig team.","schema":"{\n\t            \t'winnerId': 'integer',\n                    'options:' []\n\t            }","created_at":"2014-06-22 13:13:07","updated_at":"2014-06-22 13:13:07","pivot":{"bet_id":1,"bet_type_id":1},"userBet":""}
