min and max are expecting a value. So, this should work:

<input type=number min={{configRow.valueStart}} max={{configRow.valueEnd}}>

Here is a plunker showing a demo. (this is just a modification of the documentation demo).

At the moment, the source for these attributes looks like below. So, you can see that a value is expected that is then cast to a float with parseFloat. So interpolating the model property {{}} to a value is required.

src/ng/directive/input.js

if (attr.min) {

        var minValidator = function(value) {

          var min = parseFloat(attr.min);

          return validate(ctrl, 'min', ctrl.$isEmpty(value) || value >= min, value);

        };



        ctrl.$parsers.push(minValidator);

        ctrl.$formatters.push(minValidator);

      }



      if (attr.max) {

        var maxValidator = function(value) {

          var max = parseFloat(attr.max);

          return validate(ctrl, 'max', ctrl.$isEmpty(value) || value <= max, value);

        };



        ctrl.$parsers.push(maxValidator);

        ctrl.$formatters.push(maxValidator);

      }
