ng-maxlength not working for a variable

[jayanthakgjls]

I'm trying to use ng-maxLength directive to give a variable max-length for my inputs.

   <input type="text" ng-model="name" ng-maxlength="$metadata.maxLength" ng-required="$metadata.isRequired" name="name" /> 

But it doesn't seems to be working as expected. When it is applied the model binding for the same variable is not working. Here is my plunker http://plnkr.co/edit/NHNaswIIZqcdrOurYXVM?p=preview

If I remove ng-maxLength ng-required is going to work as expected , otherwise ng-required is also not working.

the input directive does not "parse" the ngMaxLength attribute, it only calls parseInt() on it, essentially. This is a duplicate of a number of other issues wanting various model attributes to be parsed as expressions, including #1405, #1199, and others that I'm having trouble finding right now.

I agree that this is probably an expected use case, and for numbers it probably would not break anything to "fix", but I'm not sure if it's really worthwhile most of the time.

Closing this so this can be continued on existing issues
