I create a model named "mypurchase", and in this model I add button to the view page to go to another model "mystock", pass the purchased items and their qty to "mystock".

in the scripts I make the action dict, I double checked it, make sure it's the full same as official "action" keys, without no errors.

but when I clicked the button, the page change to "mystock" successfully, but all cells are blank ----- no data values were passed to the "mystock" view page, 

pls help me, I don't know why this, thanks advanced.

my action dict as below:
