Can you call ko applyBindings to bind a partial view

Question

I m using KnockoutJS and have a main view and view model  I want a dialog  the jQuery UI one  to popup with another view which a separate child view model to be bound to   The HTML for the dialog content is retrieved using AJAX so I want to be able to call ko applyBindings once the request has completed  and I want to bind the child view model to just the portion of the HTML loaded via ajax inside the dialog div   Is this actually possible or do I need to load ALL my views and view models when the page initially loads and then call ko applyBindings once

ko applyBindings accepts a second parameter that is a DOM element to use as the root   This would let you do something like    lt div id  one  gt     lt input data-bind  value  name    gt   lt  div gt    lt div id  two  gt     lt input data-bind  value  name    gt   lt  div gt    lt script type  text javascript  gt    var viewModelA          name  ko observable  Bob           var viewModelB          name  ko observable  Ted           ko applyBindings viewModelA  document getElementById  one       ko applyBindings viewModelB  document getElementById  two      lt  script gt    So  you can use this technique to bind a viewModel to the dynamic content that you load into your dialog   Overall  you just want to be careful not to call applyBindings multiple times on the same elements  as you will get multiple event handlers attached

While Niemeyer s answer is a more correct answer to the question  you could also do the following       lt div gt     lt input data-bind  value  VMA name    gt   lt  div gt    lt div gt     lt input data-bind  value  VMB name    gt   lt  div gt    lt script type  text javascript  gt    var viewModels          VMA   name  ko observable  Bob          VMB   name  ko observable  Ted            ko applyBindings viewModels    lt  script gt    This means you don t have to specify the DOM element  and you can even bind multiple models to the same element  like this    lt div gt     lt input data-bind  value  VMA name       and     VMB name      gt   lt  div gt
