Calling a jQuery plugin in a Backbone render method

I have a render method in Backbone that goes basically like this:

render: function () {
  $.tmpl(this.template, attrs).appendTo(this.el);
  return this;
},

which is called from a router action:

action: function () {
  $('#container').empty();
  $('#container').append(myView.render().el);
},

Now, I want to apply a plugin on label elements inside this view. My first thought was to call the plugin inside render:

render: function () {
  $.tmpl(this.template, attrs).appendTo(this.el);
  this.$('label').inFieldLabels();
  return this;
},

but this doesn't work (I'm assuming this is because the element hasn't been added to the DOM yet). It does work if I call the plugin in the router action though:

action: function () {
  $('#container').empty();
  $('#container').append(myView.render().el);
  myView.$('label').inFieldLabels();
},

I'd rather not do this, because the plugin is part of the view, not the router, so it doesn't make sense to be calling it inside the action. Is there a better way to do this?
