Hero Animation in polymer 1.0

I am trying to implement hero animation(from neon-elements) to animate to another custom element(element1.html to element2.html) by clicking a red square.

I wrote everything that is documented here: https://github.com/PolymerElements/neon-animation#shared-element

But nothing happens on click. Please guide me on implementing this.

Here are my files:

index.html

<!DOCTYPE html>

<script src="bower_components/webcomponentsjs/webcomponents-lite.min.js">        </script>

<template is="dom-bind">
    <neon-animated-pages id="pages" selected="0">
        <name-tag>
        </name-tag>
        <name-tag1>
        </name-tag1>
    </neon-animated-pages>
 </template>

                    return {
                        // the outgoing page defines the 'exit' animation
                        'exit': {
                            name: 'hero-animation',
                            id: 'hero',
                            fromPage: this
                        }
                    }
                }
            },
            sharedElements: {
                value: function() {
                    return {
                        'hero': this.$.hero
                    }
                }
            }
        }

    });
    </script>

                        }
                    }
                }
            },

        }

Thanks in Advance.

You are using wrong behavior. NeonAnimationRunnerBehavior is for components who play or run the animation inside themselves. Very good example will be neon-animated-pages component, it implements NeonAnimationRunnerBehavior because it runs animations inside.
Every item which placed in neon-animated-pages has to implement NeonAnimatableBehavior, not NeonAnimationRunnerBehavior.
To run the animation we have to switch somehow between our animatable components. The "selected" attribute of neon-animated-pages help us with that. When selected = "0" neon-animated-pages shows you name-tag, when selected = "1" neon-animated-pages shows you name-tag1 component.
You want to change view after click but I don't see any click event listeners. Add click events which will change selected attribute value and it'll work.
