In jQuery I use trigger() and bind() methods to accomplish this. However, I'm not able to find anything equivalent in Ext JS. Am I missing

问题 Context I have a process that envolves creating similar file/filename structures that have inside of it the name of itself, and things like that, i do this every day, and i see that is repetitive and have a pattern, then i got the idea of creating a Sublime Text's Snippet to generate the code for me, adding a significant improvement on my performance.
