Best way to rebind data in d3.js

I am using d3.js library to generate contents based on data. Here is a simplified example. data_arr = [0,1,2,3,4]; d3.select("#mylist").selectAll('li').data(data_arr).enter().append("li").html( function(d) { var element = document.createElement('div'); element.innerHTML = '
' + d + '
'; return element.innerHTML; }); If I change my array, for example the new data is [5,3]. How is the best way to rebind and show the new html? Do I have to call the same sentence again or is it a better way? Consider the case of a more complex data structure. i.e. data_arr = [obj1, obj2, obj3, obj4]; and element.innerHTML = '
' + d.field + '
'; What happens if I do obj1.field = 'newValue'. How is the rebind done? Thanks!
