带着ROR的思想看三查，几乎被看到了沟里，几个弯始终拐不过来。比如，sancha似乎并不像ROR那样默认通过名字来绑定V和C，具体是怎么做的，我纠结了好久。今天写程序的时候终于开了窍，总结规则如下：
?
? ? // The name of controller and view does not necessary to have any relationship,?
? ? // Essentially the controller does not bind to any "view", rather than bind to
? ? // certain UI element defined in refs, by using componentSelector
? ? //
? ? // So the MVC behavor of sencha is not exactly same as in ROR, which the name
? ? // of controller and view has kind of mapping by default
? ? //
? ? // And the most important thing here, is that:
? ? // WE ACTUALLY COULD BIND A DOM EVENT OF SINGLE VIEW TO MULTIPLE CONTROLLERS,
? ? // BY DEFINE THE SAME SELECTOR!
? ? // VICE VERSA, A SINGLE CONTROLLER COULD DEFINE SET OF HANDLERS FOR DOM EVENT
? ? // SITS IN MULTIPLE VIEWS!
