Grid Master/Details in separate UI component

[Hatsuki]

Hi,
I get stuck in how to achieve the Grid Master/Details in individual Grid. Since these two Grids don't share the same Model by using the detailview, have to construct the ID for the Grid Detail through JQuery.

.Name("PricingMatrix_<#=ProductVariantsID#>")

Just wonder how could I essentially build the client binding expressions via onRowSelected() function.

$("#PricingMatrix").attr("Name", "PricingMatrix_<#=" + ProductVariantsID + "#>");

Query('#PricingMatrix').tGrid({columns:[{"title":"Price Group","member":"PriceGroup","type":"String"},{"title":"Qty","member":"Qty","type":"String"},{"title":"Amount","member":"Amount","type":"String"},{"title":"Caculate Type","member":"CaculateType","type":"String"}], total:0, currentPage:1, pageSizesInDropDown:["5","10","20","50"], pageOnScroll:false, ajax:{"selectUrl":"/Home/_SelectionClientSide_PricingMatrix?ProductVariantsID=B02D7C9E-9101-444D-9112-007BC9D6E489"},

How could I modify the ajax parameter through Jquery.
Thanks a lot for your help.
