When selecting date I get in my input element text [object Object] instead of the actual date range

[dimitriosd1983]

I believe issue is in line 109 of the file:
ngModel.$render();

If I replace that with the content of ngModel.$render = function()

if (!ngModel.$viewValue || !ngModel.$viewValue.startDate) {
return;
}
$element.val(formatted(ngModel.$viewValue));

then it works fine

see the pull requests, there is a fix you could apply locally. Unfortunately this projects doesn't look to be maintained anymore..
