uncheck default assign checked value in checkbox angular material

Question

I am bit new angular and trying to show a check box with it's value checked at page load but when I try to uncheck this checkbox after page load then it is not allowing me to do so. I am using angular material in this task.

Following is my current code.

<md-checkbox aria-label="Checkbox 1" class="green"  ng-checked="true">
</md-checkbox>

Answer 1

As per angular documentation the ng-checked value should be an expression which can hold both the true and false value. In your code your have assigned this a direct true value that is why it is not working as expected.
