  respond_to do |format|
    format.js 
  end
end

update.js.erb

$('#reloadimage').html("<%= escape_javascript( render 'users/crop' )%>");

partial _crop.html.erb

<% content_for(:head1) do %>

<%= stylesheet_link_tag "jquery.Jcrop" %>
<%= javascript_include_tag "jquery.Jcrop.min" %>
<script type="text/javascript" charset="utf-8">
$(function() {
  $('#cropbox').Jcrop({
    onChange: update_crop,
    onSelect: update_crop,
    setSelect: [0, 0, 500, 500],
    aspectRatio: 1
  });
});
</script>

This is not going to work. Remember you are manipulating HTML on the client side, the layout is already rendered.

Add your changes to the head in the update.js.erb:

$("head").append(.....);
