fix invalid container

[xtang]

hi,

I found container would be invalid when route changed, so I just select it every time when config.container is set by user. Does that make sense?

thanks.

if you're changing this logic, you should remove the other container = angular.element(config.container || document.body),

Sorry, forgot that:(

[btford]

I don't really understand the problem. This might be a good fix, but this needs an accompanying test case showing where the existing logic falls short.

@btford Sure, I will add a test case.

I think it's not the issue of btfModal, but my usage.

I followed the example in README, because the MyModal is singleton, the container seems to be binding to a block in the first directive(template) who injects the MyModal.

When I jump into the others(also injects the MyModal), MyModal's container is still in first directive element. Hope I make it clear...

thanks

Makes sense. I'm not particularly opposed to this change, but it seems like it might be better to just create a new modal instance for each controller.
