Checkbox Input bind not working properly

[raftalks]

Hi,

I am using a checkbox bind to json object where the value is numeric 1 or 0. Angularjs doesn't seem to work properly if the value of the model is numeric.

See this plunkr below and note that "value2" model obj given numeric value 1 and having the checkbox field with ng-true-value='1' doesn't make the checkbox checked.

With observation, I have noticed angular ng-true-value is actually doing '1' === 1 to model numeric value and returns false, this can work if it compares with == only. This is define in the line here I think: https://github.com/angular/angular.js/blob/master/src/ng/directive/input.js#L646

Seems like a useful issue to fix, not sure if using "==" will raise issues elsewhere though?

This is actually a dupe of #1199, so we can probably close this discussion and move it over there.
