You may not need to send parameters. Because your use of activate_page I asume that you are creating a SPA app. All the pages are already there and you can access all its elements every time from everywhere using jquery or DOM selectors.
So you may do anything before call activate_page, don't need to send parameters. What I usually do is create functions that make the processing needed before show the page and trigger these functions by the actions, like push a button or menu.
I hope this help, or post an example of what you need to do using parameters.
Thanks for answer Diego,
but i need send data populate throw 'ng-repeat' (Angular). I populated a list of items with JSON and capture the user's item click, that's data item i want to send to another view. I try with factory but no success.
I'm not familiar with Angular, but when you say that you capture the item's click, what are you doing?
If you call the activate_page, replace it with a function passing the parameters to it, and into the function do what you need with the parameters and then call activate_page.
Sorry, I'm just guessing whitout the code.
