If you need only display the trimmed value then I'd suggest against manipulating the original string and using a filter instead.

app.filter('trim', function () {
    return function(value) {
        if(!angular.isString(value)) {
            return value;
        }  
        return value.replace(/^\s+|\s+$/g, ''); // you could use .trim, but it's not going to work in IE<9
    };
});

And then

{{ foo | trim }}
